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.

comment 2

4.40pm class code = n4x58k3

If students want to do more, that’s great but please only complete the ‘Sequences’ activities in the current section they’re doing – not the Conditions, Loops and Functions, which we’ll do during the term.
