What is React JS?
What are the features of React Js?
Let’s take a look at the important features of React:
2- React Native
3- Single-Way data flow
In React, a set of immutable values between components are passed to HTML tags as properties. 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 ”.
4- Virtual Document Object Model
This framework creates an in-memory cache structure. In this structure, if a change occurs, 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?
The main question before us is why one should use ReactJs. There are so many libraries and open-source frameworks for building front-end web applications that make development easier. Let’s take a look. Advantages of React over other frameworks and technologies. In a front-end world that is changing rapidly every day, it is very difficult to devote time to learning new frameworks, especially since many of these frameworks have a very long lifespan. It is short and can not be risked over time. So if you are looking for a technology that is one of the best in its field and has the value of risk, my suggestion is 100% React.
2- Easy learning
3- Native approach
There are no pre-built containers for dependency. You can use Browserify, Require JS, and 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.
