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:

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

Multi-line comments:

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

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