Created as an efficient and easy program to use, React is extremely useful for web applications and mobile applications, used specifically for the viewing layer of applications. Read more below about what React actually is and why it is useful in the programming world.

What is React?

React.js is a library designed for JavaScript and was created by Jordan Walke when he was working as a Facebook developer. It first appeared on Facebook in 2011 and on Instagram in 2012. It is free and open-source and is used in front-end development to create user interfaces (UI) and their components. It utilizes elements to create the interfaces. It can also be utilized on the server-side when needed. Facebook, among other developers, work to maintain and update the library.

5 Reasons to Use React

There are many reasons why programmers believe this is the best way to create a user interface. Here are five great reasons why you should consider learning it to design future web pages.

1. The library can be used for both web and mobile applications.

While originally designed for web applications, React Native allows for mobile applications to be created for both IOS and Android.

2. Interactive application creation is supported.

Because it is so well established and supported, there are many tools and libraries that can be used with React to create interactive features. Tools like React DnD help create drop down menus, while Recharts works to create charts to help visualize data.

3. It allows the creation of reusable components.

Code components that have been written using this library can be used again. This saves developers time with coding while preventing coding errors, therefore enhancing the debugging speed. This also allows for consistent programming within an interface.

4. React’s Virtual Document Object Model (DOM) is faster than alternatives.

When programmers make edits to web pages, the Virtual DOM only refreshes the part of the web page’s browser with the components that have changed, rather than the usual full page refresh. This is another feature that improves programming and loading time.

5. It is very readable and easy to learn.

Since it is declarative and simple, even those not familiar with this particular library are able to read and understand the code. It was designed this way so that programming would be fast and intuitive. Familiarity with CSS and HTML is all that is truly required.

How to Download React

  • Before downloading the library, you will want to download both node.js and npm.
  • Then, create a project folder with a  package.json file.
  • Finally, install by typing the line $ npm install –save react
  • This will install the react module using npm.
  • It can be located in your files by using the command:

 var React = require(‘react’)

  • Next, install the DOM.

How to Learn React

With a supportive and established community, it is definitely possible to find tutorials and resources to learn this library on your own. However, it is often helpful to have a structured course to learn everything about this library so that you are ready to apply it to your coding practices. 

Bootcamps provide this structure through in-person, online, or hybrid formats. Many also offer internships, networking opportunities, resume assistance, and more to help you find a job that meets your career goals.
