What is React JS? ⚛️

A JavaScript Library for Building User Interfaces (UI) created by Jordan Walke(Software Engineer at Facebook) was released in the year 2013.

The User Interface(UI) is a point of Human Interaction and Communication.

It has a Huge community on GitHub and is maintained by Facebook

Key features of React JS ⚛️

1. Virtual DOM⚛️

The virtual DOM (VDOM) is a programming concept where an ideal, or “virtual”, representation of a UI is kept in memory and synced with the “real” DOM by a library such as ReactDOM. This process is called reconciliation.

2. JSX

JSX stands for JavaScript XML. It allows us to write HTML in React. JSX makes it easier to write and add HTML in React.

3. Component

Components are independent and reusable bits of code. They serve the same purpose as JavaScript functions, but work in isolation and return HTML.

Components come in two types, Class components and Function components.

4. One-way data binding

ReactJS uses one-way data binding.

In one-way data binding, one of the following conditions can be followed:

• Component to View: Any change in component data would get reflected in the view.

• View to Component: Any change in View would get reflected in the component's data.

5. Performance

React uses several clever techniques to minimize the number of costly DOM operations required to update the UI. For many applications, using React will lead to a fast user interface without doing much work to specifically optimize for performance.
