5. Git: Git is a version control system that is commonly used in React JS development. It is important to have a good understanding of Git and its basic commands to manage your code changes and collaborate with other developers.

In summary, to learn React JS, you should have a good understanding of JavaScript, HTML/CSS, ES6, Node.js and NPM, and Git. If you are new to any of these topics, it is recommended to learn them before diving into React JS.
