| # Add Comments in JSX
 | |
| 
 | |
| ---
 | |
| ## Problem Explanation
 | |
| 
 | |
| You can comment as you used to do with code blocks in JavaScript `/* some JS code */` but they need to wrapped by curly braces to add comments in JSX:
 | |
| 
 | |
| For example:
 | |
| * Single-line comment:
 | |
| ```jsx
 | |
| {/*<h1>Hanoi University of Science</h1>*/}
 | |
| ```
 | |
| 
 | |
| * Multi-line comments:
 | |
| ```jsx
 | |
| {/*
 | |
| <h1>Hanoi University of Science</h1>
 | |
| <p>Falculty of Mathematics, Mechanics and Informatics</p>  
 | |
| */}
 | |
| ```
 | |
| 
 | |
| Notice: You can't use HTML comment in JSX like this:
 | |
| ```html
 | |
| <!-- not working -->
 | |
| ```
