+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) 
+*/
+```
