React JS: What is it and where is it used?

ReactJS by Facebook and Instagram, and it’s to power some of the most popular websites in the world today. The concept behind React is simple but powerful: everything should be an object. Those objects should only represent one single thing in the real world. But what are those objects that React creates? And what does it mean when you hear someone say React makes things virtual? Find out with this beginner’s guide to React JS!

Web Applications

It is one of the most popular front-end frameworks for building user interfaces for web applications. Like AngularJS, React supports two-way data binding. It consists of a JavaScript library which helps with the interface’s logic. Separating that from the actual rendering of the interface to improve efficiency. React also uses a virtual DOM diff algorithm to detect any changes in your user interface that require updating. So that you don’t need to constantly update the HTML DOM tree. React was first released by Facebook in 2011 and has since exploded as one of the more popular UI frameworks on GitHub.

Why Do People Use React?

* React.js is scalable – It can grow with the app, being able to handle more complicated data flows with larger volumes of data. As a result, you have an easier time making changes and updates as the application grows. * Fewer Components – React components are also much smaller in size than some others because they have such little when their state doesn’t change. * Flexible – With React, programmers are able to define just what each component should render without worrying about the internal implementation details of other pieces of code that might be among several parts of an application. This makes it easier to adjust and refactor both user inte犀利士
rfaces (UI) and business logic since they exist as two distinct chunks that don’t need any interaction between them.

What Technology Does React Work With?

As a JavaScript library, React can be by web developers to create an interactive user interface. React works with any JavaScript framework, including Facebook’s proprietary framework Backbone which operates on the browser’s front end but not on the server side. 

This is because while React handles UI issues like how elements are rendered, Backbone handles routing between states. In other words, React controls what happens when your screen changes after clicking a button whereas Backbone determines what screen you’re taken to when clicking that button in the first place. 

The technical term for this interaction is ‘state’. 

For example, say you’re reading an email. The React-controlled part of the app would manage things like which text was highlighted as well as buttons that enable opening or deleting messages. The Backbone-controlled part of the app would determine what email list view to show (e.g., inbox or sent items) when viewing that email list from the home screen.

Major Advantages of React.js

Unlike many frameworks, React.js has a virtual DOM. This means that when the DOM content or style is, only the corresponding DOM element needs to be in the actual. HTML markup as to update all elements that may change if only inline styles were. React also supports higher-order components which can break down an interface into individual pieces. Higher-order components are reusable widgets of functions and templates without any implementation details (state, child behaviour, event handlers). This makes it easy to move components between projects without having to rewrite them from scratch.
