Originally developed for Facebook by the Facebook, React is a JavaScript library that builds user interfaces for single-page applications by dividing UI into composable components. Since it requires only a minimal understanding of HTML and JavaScript, React has risen in popularity as a front-end web development tool.
Before React was introduced, programming languages like Angular JS, Ember JS, and Ajax were dominating web and app development. Facebook considered the shortcomings of these languages while developing React to give front-end developers a better programming language. Facebook engineers developed React as a test tool, but the library has become the best JavaScript library for web design and development. Here are the top reasons why you should consider using React JS over other JavaScript libraries.

 

1. Fast Learning Curve

React comes with a user-friendly and easy to understand JavaScript documentation. You will easily grasp the components right away even without guidance from another developer. React uses plain JavaScript and its lifecycle is clearly defined. It is easy to use the component-based approach to build your website or mobile application. The simplicity of React makes it preferred to the complex Ember and Angular framework.The React guide indicates that Thinking in React is different from other JavaScript libraries. You need to take time and learn the new framework even if you are familiar with other JavaScript engines. However, the library becomes easier to use as you apply it often on websites and apps.

 

2. Reusable Components

React provides a component based structure. Components are your lego pieces. You start with tiny components like button, checkbox, dropdown etc. and the you create wrapper components composed of those smaller components. And then you write higher level wrapper components. And, it goes on like that until you have this one root component and that component is your app.
The major advantage of components on this JavaScript library is that you can re-use them on any platform. Consequently, your app or website will have the same outlook on all platforms. Re-usable components simplify the app development process. Also, re-usable codes enable you to grow and maintain your codebase fast.

 

3. Fast render with Virtual DOM

When you are about to develop a web application that involves high user interaction and view updates, you have to consider the possible performance issues. Although today’s javascript engines are fast enough to handle such complex applications, DOM manipulations are still not that fast. Updating DOM is usually the bottleneck when it comes to the web performance. React is trying to solve this problem by using something called virtual DOM; a DOM kept in memory. Any view changes are first reflected to virtual DOM, then an efficient diff algorithm compares the previous and current states of the virtual DOM and calculates the best way (minimum amount of updates needed) to apply these changes. Finally those updates are applied to the DOM to ensure minimum read/write time. This is the main reason behind React’s high performance.

 

4. Great tool set for developers

When choosing a development platform, it is important to consider the available tools. You also need to consider their compatibility or usability with different browsers. One of the reasons why React JS is popular among frontend developers is its toolset. You need to differentiate between two toolsets when using React Js. The first toolset is React Developer Tools while the second is Redux Developer Tools.

You can install both toolsets as Chrome extensions, but their functionalities are different. You can use React Developer Tools to inspect components in their hierarchy and observe their states and current props. Redux Developer Tools, on the other hand, are great for observing dispatched actions and current states and changes on stores. You can modify stores and dispatch actions and view the changes instantly when using the Redux library.
All changes made with the Redux Developer tools are stored within the extension. Hence, you can move your application to any previous state for debugging purposes. One thing to note about the toolsets is that they are Chrome extensions. This means that they may not function in the same way when using other browsers. You may have to install Chrome on your device to enjoy the functionality of the developer tools.

 

5. React Native

Learning React comes with a bonus: React Native. React is not a ‘write once run anywhere library’, as the creators says, it’s a ‘learn once write anywhere’ library. Yes, you can write native apps for Android and iOS using React Native. Although you will not be able to use the exact same code you wrote for web, you will be able to use the same methodology and the same architecture.

 

 

The features outlined in this section explain React’s popularity in the field web design and development. You enjoy multiple benefits including high-performance apps and websites by choosing React JS. However, you need to check the library’s visibility and crawling on different browsers. Some of its features may not be fully functional on some browsers and search engines. This means that you target users may not access all the functions of your mobile app or website. Hence, it is important to test the product on all browsers and search engines before launching it.

React JS offers multiple benefits to webmasters including a high performance with virtual DOM, easy programming language, and great developer tools. The JavaScript library is easy to understand, apply, and test. However, web developers must be careful when using the library. Some of the web pages may be invisible in some browsers and search engines.
