These mesmerizing numbers show that React.js is the most loved and wanted framework. Eventually, a career in developing applications via React.js can obviously bring difference and make your reach better. When planning for a career in developing websites, you can do this by taking up an online React.js certification course and getting certified and becoming a professional React developer.
What is React.js?
Let us see why React JS is the developer’s favorite language.
Why is React used so widely?
Basically, React is used for developing UIs or user interfaces. To use a website, you need some buttons, search bars, on-screen menus, etc. or anything else that is used for interaction, and this is what is called user-interface. Before ReactJS came into existence, creating flawless UIs was a tedious task.
In 2011, Jordan Walke, a Facebook engineer, created ReactJS precisely to improve the development of these UIs. so, you can conclude that ReactJS is used exclusively for programming and designing the “front-end”.
It saves the development time and also minimizes the chances of coding errors by providing you with a reusable React library code. In addition, there are two key features that make ReactJS special, which are
- Virtual DOM
Basically, a website has HTML documents at its core. These documents are displayed as web pages by your web browser. During this process, web pages are arranged by web browsers in the form of Document Object Model or DOM. When some modification is required, instead of editing the whole website, developers can modify DOMs to add the dynamic content to their project.
The DOM works when the changes are small and the website is static. But when it comes to dynamic websites with excessive user interaction, DOM doesn’t work efficiently.
Here, a developer utilizes JSX to exploit and update its DOM as React creates a virtual DOM. Now, what is virtual DOM?
The virtual DOM is a copy of the website’s DOM. React refers to this virtual DOM to carry out changes into actual DOM.
Why Should you Learn React?
When it is required to build large web applications in an agile manner, react is an ideal language that is the preferred choice of web developers. When you need to update the web pages, you don’t need to reload the page, the data gets updated dynamically.
Advantages of learning ReactJS
- Easy to learn
Being a lightweight library, ReactJS lets you start creating interfaces when you learn the fundamentals of the language. It is related to the application view layer only.
You are not required to learn patterns like MVVM, the abstraction takes place if you are acquainted with the lifecycle, props, and state of the forms.
- Virtual DOM
React significantly reduces the time for carrying out modifications by creating virtual DOMS. when user interfaces are considered, performance issues are the first thing that a developer comes across. Virtual DOMs remove bottlenecks that communicate changes and triggers and compare the present and previous states of virtual and actual DOMs.
- Supported by Flux Architecture
Flux is a web building architecture of Facebook. It helps to optimize ReactJS in the unidirectional flow of data. With flux, data to be displayed is preserved in stores whose function is to sync the data across the application.
- React Native
The native applications for mobile such as Android OS are built by using ReactJS.
The other advantages of React are that it contains amazing developer tools that are available as Chrome extensions. In addition, the components in ReactJS are reusable.
The average annual salary of a ReactJS developer is $68,153 per year. Apart from the benefits of learning ReactJS, the salary of a UI developer using React is also attractive.
Top websites such as Dropbox, Cloudflare, BBC, Yahoo, PayPal, and many more are the leaders among around 1.06 million websites using React.
Obviously, you can have a lucrative career in UI building if you add a ReactJS certification to your resume. If you want to get certified, the best path you can go through is to enroll yourself in an online training course that makes sure you get certified in the very first attempt of taking the exam.
Wish you all the best.
