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 comment.
- The slash-star-star-slash comment will comment out everything between the
/*
and the*/
characters:
/* This is also a comment */
