What is React JS?
What are the features of React Js?
Let’s take a look at the important features of React:
Single-Way data flow
In React, a set of immutable values between components is passed as properties to HTML tags. Components can not directly change any properties, but can pass them to the call back function and Help them make changes. This process is complete with “properties flow down; actions flow up ”.
Virtual Document Object Model
React creates an in-memory cache structure. In this structure, if a change has occurred, it updates the DOM. This feature enables the programmer to rerender only the component that has changed in a wtpi change. A virtual DOM, like the DOM, is a tree of nodes. It contains the elements and attributes and the content as objects. The render () method creates a tree of React components and the change in each component causes this node to be updated.
Why React Js
Now, the main question before us is why should one use ReactJs. There are many libraries and open-source frameworks for building front-end web applications that make development easier. Let’s take a look at the advantages that React has over other frameworks and technologies. In the front-end world, It changes a lot every day, it is very difficult to spend time on new frameworks, especially since many of these frameworks are very short and can not be risked over time. So if you are looking for a technology that is one of the best Be it your own domain and have the value of risk, we suggest 100% React.
There are no pre-built containers for dependency. You can use Browserify, Require JS, EcmaScript 6 modules using Babel, which is automatically added to dependencies.
ReactJS applications are incredibly easy to test, so we can check our functions and components by passing parameters, states, and outputs.
