Challenge 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 */
