title: Comment Your JavaScript Code
|

Comments are a great way to leave notes to yourself and to other people who will later need to figure out what it does. Any code in it will be ignored.
|
||
|
|
||
|
Let's take a look at the two ways you can write comments in JavaScript.
|
||
|
|
||
|
* The double-slash comment will comment out the remainder of the text on the current line:
|
||
|
|
||
|
`// This is a single line comment.`
|
||
|
|
||
|
* The slash-star-star-slash comment will comment out everything between the `/*` and the `*/` characters:
|
||
|
|
||
|
```javascript
|
||
|
/*
|
||
|
This is
|
||
|
a multi-line comment
|
||
|
(comment block)
|
||
|
*/
|
||
|
```
