Those can be used also on, for example, java system, but it is always a bit hacky. There are plenty of additional JavaScript ecosystem related tooling that also come with Node.js. There are, of course, other reasons, JSX thing is just one of the first. Most of such tools are node based, so that's one of the reasons Node.js is often used. What's more efficient is to compile JSX while building the site, server side. You can use for example babel-standalone to help browsers cope with JSX, but that means that your JSX code will be compiled again on every page load, which isn't efficient. JSX will not work in browser just like that. The answer is no - Node.js is not needed - but one of the first reasons you will encounter it is often used is that people prefer to use JSX format when writing React. Does React really need Node.js on the frontend ENV? In other words, React entirely focuses on ‘View’ which describes the User Interaction part. While the React’s brothers (Angular, Ember, Backbone) are dubbed as client-side MVC frameworks, React is different. React will internally convert this into a virtual DOM, and will ultimately output our HTML for us. ![]() JSX allows us to write our components using HTML, whilst mixing in JavaScript events. ![]() React allows us to write components using JSX. This will help you to maintain the code when working on larger scale projects. You need to think of everything as a component.
