Single-line comment

One-line comments begin with / /.

Any text between / / and the end of the line will be ignored by JavaScript (will not be executed).

This example uses a single-line comment before each line of code:

Example

/ / change the title: document.getElementById ("myH") [xss_clean] = "my first page"; / / change paragraph: document.getElementById ("myP") [xss_clean] = "my first paragraph."

This example uses a single-line comment at the end of each line to explain the code:

Example

Var x = 5; / / declare x, assign 5var y = x + 2; / / declare y, thank you for reading this article carefully.
