What is React?
What is React?

React is the most popular JavaScript front-end framework in use today. It’s used by both established companies and new startups.

React was released by Facebook in 2013, and they still use it today for many of their applications. If you’re new to React, this article will help introduce you to the basics. Or, if you’d rather learn by doing, you can jump right in with our Learn React course.

What is React used for?

React is a JavaScript library for creating user interfaces. Here are three places you’ll find it being used:

Web development

This is where React got its start and where you’ll find it used most often. React is component-based. An example of a component could be a form or even just a form field or button on a website. In React, you build up complete applications using components like these by nesting them.

Components in React can manage their own state and communicate that state to child components. By “state,” we mean the data that populates the web application.

An example would be a user profile form that holds the state of the user’s data, including first name, last name, and other values. This form component would have nested field components that it passes its state to in order to populate them.

Components in React are also reusable, which means you can use one button component for every button on your site. If you need the button to look different, you can simply change its style.

Mobile app development

React Native is a JavaScript framework that uses React. With React Native, developers can apply web-based React principles to creating mobile apps for Android and iOS. Here, React is used to connect the mobile user interface of the application to the phone’s operating system.

Desktop app development

Developers can also use React with Electron, another JavaScript library, to create cross-platform desktop apps. Some apps you may know about that are built with Electron include Visual Studio Code, Slack, Skype, Discord, WhatsApp, and WordPress Desktop.

React example

Let’s look at a React example so you have a better idea of how it works. A React web application runs on one web page. Here’s an example of an HTML file used to run a React app:

Using script tags, we import the JavaScript libraries necessary for React to run. React and React DOM are the basic React libraries we need. Babel is a JavaScript library that compiles the JSX language that React uses into JavaScript the browser can understand.

The div element that has the root id is where the whole React app will run. And the script tag below that is where all the React code will go, which we’ll look at in more detail next.

To use React, you need to create components that use JSX. Below is an example component:

function Heading(props) { return 
{props.value}
; }

The component above is a simple JavaScript function that accepts a parameter called props — a special keyword in React used to pass data between components.

The function returns the value attribute of props wrapped with what looks like an HTML h1 tag. This isn’t actual HTML, yet. It’s called JSX, a React-specific syntax that allows HTML-like text to co-exist with JavaScript.

Below, we have another component that uses our Heading component. In fact, it uses it three times to create headings with different values. Note that the props in React are passed to child components as attributes of the JSX.

function App() { return ( 
    
 ); }

You’ll also notice that the name of this component is App. This is because it’s our complete application. Everything in React is a component, including the whole application. To render this app to the browser, we need one more piece of code.

ReactDOM.render( , document.getElementById('root') );

This code tells React to render the results in the HTML element that has the root id.

React vs. Angular

React is often compared to another JavaScript framework called Angular, but there are a lot of differences between the two. Here’s an overview of some of the main distinctions between the two frameworks:

  • Web development: Angular is a complete front-end framework for building web applications. It’s based on the MVC (Model-View-Controller) pattern. React, on the other hand, is for creating user interfaces — or just the View part of this pattern. This means you’ll need other libraries or more code to create complete web apps, but you’ll also have greater customizability for your features and structure.
  • Updates: Angular operates directly on a web page’s DOM, so the entire page must be updated when a change is made to its data model. React updates the virtual DOM. These updates are quicker because they don’t trigger changes in the page layout itself. Plus, once React updates the virtual DOM, it’s then compared to the real DOM, and only those parts that differ are updated — allowing for faster rendering and performance.
  • Data binding: Angular uses both one- and two-way data binding, while React only uses one-way. With Angular, changes in data can trigger changes in the view and vice versa. But, with React, data only flows in one direction — which makes debugging an app easier.

How to learn more about React

So, now you know a little about React and why developers use it to build applications. If you’re ready to learn more about React and start building front-end web applications, our Learn React course will teach you the framework’s fundamentals and essential concepts.

10 Swift Interview Questions To Practice
10 Swift Interview Questions To Practice

Swift is a coding language developed by Apple that’s used in iOS and macOS. It’s easy to read and maintain, making it a great first language. Once you’ve mastered Swift, your next step is to land a job where you can put your skills to work.

Potential employers that use Swift need to know that you’re proficient with the language. So, they may ask questions about its features and concepts during your interview. They may also ask you to use Swift to solve a coding problem during a technical interview. To help you prepare, here are 10 interview questions that’ll test your understanding of Swift.

10 Swift interview questions

While it’s impossible to know exactly what your interviewer will ask, the questions below will give you a solid foundation. They’ll give you a sense of what you’ll need to explain and gauge your familiarity with Swift’s underlying features.

1. Explain the similarities and differences between class and structure

Both structures and classes:

  • Define properties to store values
  • Define initializers to set up their initial state
  • Can be extended
  • Define subscripts to provide access to their values using subscript syntax
  • Can conform to protocols
  • Can work with generics

Classes can do some things that structures can’t. For example, they can inherit other classes’ characteristics and free up assigned resources by deinitializers.

The primary difference between the two is that classes are reference types and structures are value types. Reference types share one copy of data, so when one instance is changed, the other is changed as well. Value types make unique copies of data, so if one instance is changed, the other remains unchanged.

2. Explain the difference between nil and .none

This one’s a bit of a trick question. There’s no difference between nil and .none. Still, you may want to note that nil is used more frequently.

3. What is an optional? What problems do optionals solve?

An optional can either have value or be nil. They can be used for both reference and value types. Objective-C, a precursor to Swift, only allowed the absence of value for reference types. Swift extends that to value types.

Optionals also make your code safer and less likely to fail. They’re written by adding a question mark after the type annotation.

4. What are generics? What purpose do they serve?

Generics allow you to write reusable functions and types that can work with any type. They allow you to write code that avoids duplication. Swift’s standard library uses generics heavily. For example, Array and Dictionary are both generics.

5. Explain what a protocol is in Swift

According to Swift.org, a protocol “defines a blueprint of methods, properties, and other requirements that suit a particular task or piece of functionality.” Other classes adopt the protocol and provide implementation. A class that satisfies the rules of a protocol conforms to that protocol.

6. Explain the difference between raw values and associated values in Swift enumerations

An enumeration is a collection of values that belong together. Raw values are used to associate constant values to enum cases. An associated value is used to bind arbitrary data to an enum case.

7. What’s the difference between static and class modifiers?

The static modifier makes a property or function static, which means it’s not overridable and can’t be changed by subclasses. The class modifier can be overridden by a function or property when needed.

8. What is a module?

A module is a single unit of code distribution. Swift treats each build target, like frameworks, as a separate module with its namespace and access controls.

9. What are the access levels in Swift?

Swift has 5 access levels:

  • Open access: This is the least restrictive access level. It enables classes and methods to be subclassed and overridden within the same module and outside the module.
  • Public access: This level makes an entity accessible to other parts of code inside the same module and other modules.
  • Internal access: This is the default access level given to all entities unless you mark it otherwise. Entities marked as internal access are accessible in the scope of their defining module but inaccessible to any source files outside the module.
  • File-private access: Entities marked as file-private can be seen and accessed by any other entity inside the same source file.
  • Private access: This is the most restrictive access level. Entities marked as private are only accessible inside their defining type or source file.

10. What are the control transfer statements in Swift?

Control transfer statements are keywords that allow you to transition control from one piece of code to another. Swift has 5 control transfer statements:

  • Break: This ends the program execution of a loop, if statement, or switch statement.
  • Continue: This ends the program execution of the current iteration of a loop statement and returns control to the next iteration of the loop.
  • Fallthrough: This causes program execution to continue from one case in a switch statement to the next case.
  • Return: This causes program execution to return to the calling function or method.
  • Throw: This is used in propagating errors using throw functions.

Word of the Day: flout

1. treat with contemptuous disregard

2. laugh at with contempt and derision

_________

The word flout has appeared in 85 articles on NYTimes.com in the past year, including on July 20 in “Women’s Handball Players Are Fined for Rejecting Bikini Uniforms” by Jenny Gross:

Norway’s women’s beach handball team was fined by the European Handball Federation on Monday, after players wore shorts, instead of the required bikini bottoms, during a game over the weekend.

… Norway’s team had been planning for weeks to flout the rules to point out the double standard for female athletes. The players wore shorts for Sunday’s bronze medal game against Spain at the European Beach Handball Championships in Varna, Bulgaria.

“I don’t see why we can’t play in shorts,” said Martine Welfler, one of the Norwegian players. “With so much body shaming and stuff like that these days, you should be able to wear a little bit more when you play.”

If You Could Have Any Animal Feature, What Would It Be?

If You Could Have Any Animal Feature, What Would It Be?

What do you know about elephants and their trunks?

Watch the nine-second video embedded above of Kelly, a 34-year-old female African elephant at the Zoo Atlanta, using suction to grab a tortilla chip.

Impressed? Does it make you wish you had a trunk?

In “Elephant Trunks: Is There Anything They Can’t Do?” Richard Sima writes about a new study about the power and wonders of an elephant’s most defining appendage:

An elephant’s trunk is a marvel of biology. Devoid of any joints or bone, the trunk is an appendage made of pure muscle that is capable of both uprooting trees and gingerly plucking individual leaves and also boasts a sense of smell more powerful than a bomb-sniffing dog’s.

Elephants use their trunks in a variety of ways. They use it to drink, store and spray water, and they also blow air through it to communicate — their 110-decibel bellows can be heard for miles.

“It’s like a muscular multitool,” said Andrew Schulz, a mechanical engineering doctoral student at the Georgia Institute of Technology.

In a study published Wednesday in The Journal of the Royal Society Interface, Mr. Schulz and his colleagues reported on how elephants can use their trunks for yet another function: applying suction to grab food, a behavior previously thought to be exclusive to fishes.

Despite the ubiquity of elephants in children’s books and nature documentaries, there are numerous gaps in scientific knowledge about the biomechanics of their trunks that the new study helps fill. For example, the most recent detailed account of elephant trunk anatomy is a hand-drawn monograph that was published in 1908, Mr. Schulz said.

Contrary to popular belief, the trunk does not act like a straw.

“What they do is actually drink water into their trunk and they store it,” Mr. Schulz said. “So the elephant trunk is actually like a trunk.”

Students, read the entire article, then tell us:

  • If you could have any feature of any animal — at least for a day — what would it be and why? Eight arms like an octopus? Gills to allow you to breathe underwater? Bat ears for echolocation in the dark? The ability to change color and camouflage like chameleons?

  • What’s your reaction to the article and the videos featured in it? Do you agree with Mr. Sima that “an elephant’s trunk is a marvel of biology”? What aspect of the animal’s versatile and superstrong trunk most fascinates you?

  • The author says that much about elephants and their trunks is still unknown. What animal feature would you like scientists to research further and why?

  • What animal are you most like? Do you think that you resemble any particular animal, either in personality, behavior, characteristics or even looks? What qualities do you possess that you think animals might want to trade with you?

Learn more about Student Opinion here and find all of our questions in this column. Teachers, see how you can incorporate this feature into your classroom routine here.

Students 13 and older in the United States and the United Kingdom, and 16 and older elsewhere, are invited to comment. All comments are moderated by the Learning Network staff, but please keep in mind that once your comment is accepted, it will be made public.

Lesson of the Day: ‘She Was Declared a Witch at Salem. These Middle Schoolers Want to Clear Her Name.’

Featured Article: “She Was Declared a Witch at Salem. These Middle Schoolers Want to Clear Her Name.” By Neil Vigdor

In 1693, Elizabeth Johnson Jr., a young woman living in what is now North Andover, Mass., was convicted of witchcraft. Unlike the vast majority of other people who were wrongfully convicted at the Salem witch trials, Ms. Johnson’s conviction was never overturned. This year, an eighth grade civics class set out to clear her name.

In this lesson, you will learn about the Salem witch trials and how a group of middle schoolers put their civics skills to the test in an effort to exonerate Ms. Johnson. Then, you will write a letter supporting or opposing a bill that could rewrite history.

Jot down what you know about the Salem witch trials. What were they? Where did they happen? Why did they happen? Who was often accused of being a “witch”? How were the accused treated?

Then, watch this two-minute video from NBC Learn and add at least three more key facts about the witch trials to your list:

Read the article, then answer the following questions:

1. Summarize the life of Elizabeth Johnson Jr. in a few sentences. Based on the article, why might she have been convicted of witchcraft? What does that tell you about the fears or prejudices held by people during that time period?

2. Carrie LaPierre, the teacher of the eighth grade civics class at North Andover Middle School taking up Ms. Johnson’s cause, said they were learning about “acceptance” in class. Why might learning about acceptance be important in a class about government? How might it relate to the Salem witch trials?

3. In what ways did the witch trials affect the communities of Salem and the surrounding towns? What effect did it have on Ms. Johnson’s family?

4. According to Emerson W. Baker, a history professor at Salem State University in Massachusetts, what are some of the reasons that people were so afraid of the idea of witches?

5. What efforts have been made over time to right the wrongs of the Salem witch trials? Do you think these actions are enough? Why or why not?

6. How was Ms. LaPierre’s class able to learn from the process of trying to exonerate Ms. Johnson? Would you be interested in learning about the government through a project like this?

In March, State Senator Diana DiZoglio, who had been working with Ms. LaPierre’s class, introduced a bill to clear Elizabeth Johnson Jr.’s name. You can read it here.

Do you support or oppose the exoneration of Ms. Johnson? Why? Write a letter to Ms. DiZoglio explaining your position. In your letter, make a clear case for why you support or oppose the bill and use examples from the featured article or your own research to help convince the legislature to take your side. Then, if you like, you can send your letter to Ms. DiZoglio’s office.

Additional Teaching and Learning Opportunities

  • Analyze primary sources. Read the two original examinations of Ms. Johnson, and use these questions to help you analyze them and think about their significance today.

  • Consider the meaning of historical, and contemporary, “witch hunts.” What does that term mean to you? What do you think of when you hear it? Watch this video on the history of witch hunts. Then, take a look at any of these three examples of modern-day “witch hunts”:

    “What a Witch Hunt Really Looks Like,” a guest essay on former President Donald J. Trump’s invocation of the term during the investigation into Russian interference

    “Fighting Modern-Day Witch Hunts in India’s Remote Northeast,” a four-minute video about accusations that have led to violence against women

    “Memories of a Real ‘Witch Hunt,’” one woman’s story of her father, who was swept up in the anti-communism sentiment of the 1950s, which many considered a “witch hunt”

    What connections can you make to the origins of witch hunts or the Salem witch trials? What other examples of modern-day “witch hunts” can you come up with? What further questions does the term raise for you?

  • Learn about the reclamation of the “witch” label. Read an article about witches in popular culture, an interview with a Brooklyn-based witch, or a personal narrative on what it means to be a witch. Do you identify with being “witchy” in any way? Are there people in your family or community who are proud of the ways they are able to heal or help others with witchcraft or supernatural powers?

Lesson of the Day: ‘What Will Become of Afghanistan’s Post-9/11 Generation?’

This Lesson of the Day will help prepare students to participate in our live panel on Sept. 30 at 1 p.m. Eastern about how Sept. 11 shaped the generation that grew up in its aftermath. You can register for the event here, and you can submit your questions here — we might use them during the panel.

Featured Article: “What Will Become of Afghanistan’s Post-9/11 Generation?” — a photo essay by Kiana Hayeri

In April 2021, President Biden announced that American troops would withdraw from Afghanistan by Sept. 11, 2021. Following the announcement, Kiana Hayeri, a photojournalist, began documenting the end of the 20-year occupation from the perspective of young Afghans who were raised in the decades after the U.S. invasion in 2001.

In this lesson, you will see the ways in which six young people who had lived in a world of new freedoms and opportunities suddenly found themselves in a changed world with the rise of the Taliban. Then, you will write a letter to one of the young people from the article, or to their family, sharing the ways in which you connected with their story.

Discuss as a class or in small groups:

  • What do you know about the war in Afghanistan? What about the U.S. withdrawal of troops and the Taliban takeover?

  • Where have you received your information? News articles? Social media? Talking with friends and family?

  • What questions do you have about what is happening?

If you need more information or context about what is happening, start with our Lesson of the Day about America’s longest war — its causes and its consequences.

The featured article focuses on the stories of young people. Watch this video of three young women sharing their stories of living in Afghanistan now, and then respond to the questions.

  • What is one emotional reaction you had to the video?

  • What is one thing you learned from the video?

  • What is one question you have after watching the video?

Read the article, then answer the following questions:

1. The writers describe the ways in which the lives of young Afghans are rapidly changing. What is one example or description from the introduction that helps you to understand and visualize those changes?

2. The article begins with the story of childhood friends, Karim, Gul Ahmad and Saeed. What is one way that you connected to their story of work and friendship? Choose one image and one quote that you think best illustrate that theme.

3. When asked what he wanted to be when he grew up, Gul Ahmad laughed. Based on the article, why do you think he responded that way?

4. What were Esmat’s hopes and dreams for himself and for his family? Why do you think Esmat both hoped for a future, but was also aware he might not live to see the future? Does that make you think of anything else you have read, seen or experienced?

5. How did the subject matter of the play that Maryam performed in become even more relevant for her and the other actresses? What does that story, both in real life and in the world of the play, demonstrate about fears that young women, like Maryam, have?

6. How did Naser Khan take a stand for his country? How did that place him in a dangerous situation during the U.S. withdrawal?

7. The article ends describing Kiana Hayeri’s last days in Kabul. As you read about her experiences leaving Afghanistan, what more do you want to know? Think of a question you would like to ask Ms. Hayeri and submit it as a 30-second video using this form.

In the featured article, Maryam, 17, said to Kiana Hayeri, the photographer, “If you’re writing about this, please tell about the situation of Afghanistan.” Why do you think Maryam felt it was important to share that with Ms. Hayeri? And why do you think Ms. Hayeri chose to include her plea in the essay?

Write a letter to one of the young people in the featured article. In your letter, let that person know what you learned from the stories and photographs of young people in Afghanistan. You can share how it felt to read the words and see the faces of people living there now, and you can also let the person know how you personally connected to the stories you read. Then, ask one or two questions about that person’s life or current circumstances.

You can share your letter in the comments section of this article.
