How to write comments in React?

The comments in React/JSX are similar to JavaScript Multiline comments but are wrapped in curly braces.

Single-line comments:

<div>
  {/* Single-line comments(In vanilla JavaScript, the single-line comments are represented by double slash(//)) */}
  {`Welcome ${user}, let's play React`}
</div>

Multi-line comments:

<div>
  {/* Multi-line comments for more than
   one line */}
  {`Welcome ${user}, let's play React`}
</div>

You can use // and /* */ in JS logic, hooks, and functions.
