It is specially used for develop single page applications. It’s used for handling frontend for web and mobile applications. React Js also allows us to create reusable User Interface components. React Js was first time created by Jordan Walke, who is software engineer at Facebook. React Js first time used in deploying on Facebook’s newsfeed in 2011 and on Instagram.com in 2012.
React Js allows developers to create large single page web applications which can change data, without reloading the page. The main purpose of React Js is to be fast, scalable, and simple. It works only on frontend handling in application.
What are the ReactJS Features?
React embraces the fact that rendering logic is inherently coupled with other User Interface logic: how events are handled, how the state changes over time, and how the data is prepared for display.
React Js has native libraries which were announced by Facebook in 2015, which provides the react architecture for native applications like IOS, Android and UPD.
Single-Way data flow
They are multiple programming patterns of structuring your react application when managing state. One-way-data-flow ←- redux, and unidirectional way ← parent to child.
Virtual Document Object Model
React creates an in-memory data structure cache which computes the changes made and then updates the browser. This allows a special feature which enableprogrammer to code as if whole page is render on each change where as react library only render components which actually change.
Why React Js?
Now, the main question arises in front of us is why one should use ReactJS. While other technologies such as Angular were available when Facebook developed ReactJS, most developers were forced to do a lot of coding. Developers using other frameworks have the challenge of having to rework on most codes even when crafting components that changed frequently.
React JS provided the solution that developers were looking for. It uses JSX (a unique syntax that allows HTML quotes as well as HTML tag syntax application for rendering specific subcomponents) This is very helpful in promoting construction of machine-readable codes and at the same time compounding components into a single-time verifiable file.
- Simple to learn
Anyone with a basic previous knowledge in programming can easily understand React while Angular Js and Ember Js are referred to as ‘Domain specific Language’, implying that it is difficult to learn them. For react you just need basic knowledge of CSS and HTML.
- Native Approach
React can be used to create mobile applications. And React is a diehard fan of reusability, meaning extensive code reusability is supported. So at the same time we can make IOS, Android and Web application.
ReactJS applications are super easy to test. React views can be treated as functions of the state, so we can manipulate with state we pass to the ReactJS view and take a look at the output and triggered actions, events, functions, etc.
