This article outlines how to comment in JavaScript. There are two types of comments in JavaScript single line and multi-line.
Single Line //
<script type="text/javascript"> // This is a single comment line var test = "test"; // This is a comment after a line </script>
By placing a double forward slash in place before text you are creating a section ignored by the JavaScript interpreter. While this is useful in the cases where you have a small amount of information to share when you want to block out a large piece of your code or where you want to add a detailed comment to a piece you require Multi-line comments.
Multiple Line /* */
In this case were are using /* to open a comment and closing with */ everything between these are ignored.
<script type="text/javascript"> /* This is a Multiline comment */ /* This is blocking out some code var test2 = "test2"; var test3 = "test3"; var test4 = "test4"; */ var test1 = "test1"; </script>
