What is React.js?

by Harry Newman

React was created by Facebook to increase efficiency to the Facebook app.  Back in 2011, the maintenance of the Facebook app was having issues keeping up with the heavy influx of updates. The upgrade for the code came in the form of React js.

What is it then?

React.js is a JavaScript library that enables a more simple way to develop web apps than JavaScript or other libraries such as JQuery. React gives Front End developers a way to create user interfaces that focus on a seamless interaction with the user.

Benefits of React.js:

  • Interactive Components
  • Reusability
  • Enhanced search functions

It eases developers lives by allowing them to code in a simpler way. Instead of making the interface as a whole React allows you to break the interface in small blocks called components. These components are anything that you want to program into your interface from the search box to any button and element.

Being a library for building user interfaces react has its own Virtual DOM that allows rendering to be faster and more efficient. This works because the Virtual DOM has an integrated algorithm that detects component changes and enacts independent component rendering. This skips a render for the interface as a whole.

Improvement is real

In today’s day and age web and mobile app development need great user interfaces React will help you to this goal. Even though React is limited to UI, there are ways to create a great project combining React.js and Angular.js taking advantage of the powerful render capabilities react brings to the table.


React is not a framework but a JavaScript library. When used correctly, this library allows a better render and coding experience. It can give your users a better experience and interaction with any app or project you are developing at the time. A great asset to have under your sleeve if your web development skills need a friendly approach to UI.

React applications are limited to the cover view of your apps. It has pros and cons like everything, but it definitely adds up to the JavaScript framework.

    Vue.js is replacing Angular and React in many cases. This brings in the topic of this blog ‘Vue.js is good, but is it better than Angular or React?’
