JavaScript: Comments

One-line comments start with two forward slash characters //

comment 1

Multi-line comments start with a forward slash and an asterisk   /*  and end with an asterisk and a forward slash   */

The content of comments is ignored, so if we put code inside /* … */, it won’t execute.
