Why use React?
- It’s fast: React uses a virtual DOM that only updates the real DOM when it has to; this makes your pages load faster.
Pros of React.js
This makes updating the UI much quicker than traditional approaches where each element needs to be rebuilt from scratch every time something changes (which means redrawing everything). This also reduces memory usage because there’s no need to hold onto all those old versions anymore!
Cons of React.js
React.js is not a complete framework, it is just a view layer. This means that you will have to use additional libraries or frameworks to build applications with React.js. The most common ones are Redux and MobX (which we will talk about later).
Creating a Dynamic Website with React.js
React has some drawbacks too; its learning curve can be steep if you’re new to front-end development, but once you get past this initial hurdle it becomes much easier because there are fewer concepts involved in working with React compared with other libraries like Angular 2+.
Optimization and performance
To optimize your React applications, you need to know how to use it with Webpack and Babel. You can also optimize your application by using ES6 features, JSX and CSS.
- Using React with Webpack: This will enable you work on large-scale projects and develop websites quickly by splitting up files into modules that can be loaded individually or together asynchronously based on their dependencies (React components).
Building React applications using modern tools
In this section, we’ll cover the tools that you need to create modern web applications with React.js.
- Create-React-App: This tool creates a new project with all the necessary files and dependencies configured for you in just one command.
- Babel: Babel turns ES6 (ES2015) into regular old ES5 so that browsers can understand it today instead of waiting until 2020 when all browsers will support ES6 natively without any transpilation steps needed beforehand.
We hope this article has given you a better understanding of what React.js is, what it can do for your project and why it’s so popular among developers today. We also covered some of the drawbacks with using this framework so that you can decide whether or not React is right for your next project!
