10 Reasons to Learn ReactJS in 2021

If you do learn Node first and can set up a basic server, this means you now have the capability of combining Node and React and creating full-stack applications. If you learned React without Node, it may be tricky to get a good understanding of how React is used with backend technologies and its full potential. Meaning you will not have a full understanding of React without learning a backend technology like Node. For that reason, the learning curve for writing code in, and understanding Node is probably slightly easier than tackling a frontend framework like React.
