Why Use React JS? 2020 Smart New Guide

You probably know React JS, a web and app development tool created by Facebook that quickly became one of the most used JavaScript libraries in the world. But it isn’t just known because it was made by Facebook; this tool has been very well received for its many uses. This article is for those who are asking themselves, “Why use React JS?.
Today, React remains one of the most trusted technologies for building scalable, high-performance digital products. Whether you’re launching a startup MVP or developing enterprise-grade platforms through professional Website Development Services, React’s flexibility, component-based architecture, and extensive ecosystem make it an excellent choice for creating modern web applications that are easy to maintain and scale over time.
You might be interested in What is React JS?
Before we start, let’s take a quick recap of what React JS is. This web and app development tool is a JavaScript library, which means that it allows developers to create, store, and share JavaScript components. It is primarily used to design and build User Interfaces and web applications.
4 Reasons to use React JS:
Beginner-friendly
One of the most well-known virtues of ReactJS is that it is very beginner-friendly and is even recommended for inexperienced developers who want to build their JavaScript skills. Even though React uses JavaScript, you don’t need to be an expert to use it. Having a good grasp of its basics will do.
ReactJS also uses HTML and CSS, along with JavaScript, which are among the easiest languages to learn. These languages are also widely used to create web applications, and if you already know them, then you can use React to create web applications in no time.
JSX
JSX, which stands for JavaScript XML, is one of ReactJS’s main features. In case you’re wondering why that is so useful, JSX allows developers to shape their DOM using HTML-like code. While JSX isn’t necessary in React, its use can help develop a more useful and adaptable tool.
Virtual DOM
Any website that isn’t using ReactJS will use HTML to reflect changes made to its DOM. This might not seem important at all if you’re developing a simple website that displays static data, but it becomes troublesome if you’re developing a complex website that constantly needs to update its data in real time.
Why? Because HTML needs to reload the entire DOM every time someone interacts with something. This makes websites sluggish and less interactive, as users need to click to see any updates.
Whenever a website is built with JSX, ReactJS creates a Virtual DOM. This is a copy of the website’s DOM, which will be used to compare any changes made against the original DOM.
Every time something changes in the Virtual DOM, it is compared to the original, and only the changed section is updated. This allows developers to create more interactive and intuitive web applications, and also makes websites require less computing power.
React Native
While React Native isn’t exactly the same as React JS, it’s based on it. The main difference is that, instead of being used to develop websites, it is used to create mobile applications. This allows developers who are well-versed in ReactJS to dwell in the world of app development.
It also allows developers to reuse code written for web applications to build their own mobile apps, speeding up development. The best part is that it can be used to develop apps compatible with both Android and iOS, making it a very versatile and useful tool.
While there are many more reasons to use ReactJS, these are the most prominent ones. As you can see, this is a very solid tool that should be adopted and used by developers who want to expand their skill set and their careers.
