We can add comments to interpret the JavaScript or improve the readability of the code.

One-line comments begin with / /.

This example uses single-line comments to explain the code:

Example

/ / output title: document.getElementById ("myH1") [xss_clean] = "Welcome to my home page"; / / output paragraph: document.getElementById ("myP") [xss_clean] = "this is my first paragraph."

The following example uses multiple lines of comments to explain the code:

/ * the following code will output a title and a paragraph and will represent the beginning of the home page * / document.getElementById ("myH1") [xss_clean] = "Welcome to my home page"; document.getElementById ("myP") [xss_clean] = "this is my first paragraph."
