What is React ?

React is a flexible JavaScript library that is both declarative and efficient for building new user interfaces. React allows you to design and develop complex UIs from very small and isolated pieces of code referred to as “components”. React has a lot of variants in its components offering. React helps with the reusable UI components’ creation. These components present data that alters over time.

React is a component-based library which is used to develop interactive UI’s (User Interfaces). It is currently one of the most popular JavaScript front-end libraries which has a strong foundation and a large community supporting it.

React allows developers to create large web applications which can change data, without reloading the page. The main purpose of React is to be fast, scalable, and simple. It works only on user interfaces in application. This corresponds to view in the MVC template. It can be used with a combination of other JavaScript libraries or frameworks, such as Angular JS in MVC.


Features of ReactJS

Let us take a closer look at some important features of React

  • JSX
    In React, instead of using regular JavaScript for templating, it uses JSX. JSX is simple JavaScript which allows HTML quoting and uses these HTML tag syntax to render subcomponents. HTML syntax is processed into JavaScript calls of React Framework. We can also write in pure old JavaScript
  • React Native
    React has native libraries which were announced by Facebook in 2015, which provides the React architecture to native applications like IOS, Android and UPD.
  • Single-Way data flow
    In React, a set of immutable values are passed to the components renderer as properties in its HTML tags. Component cannot directly modify any properties but can pass a call back function with help of which we can do modifications. This complete process is known as “properties flow down; actions flow up”
  • 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 enable programmer to code as if whole page is render on each change where as react library only render components which actually change.
