JavaScript comments are written using double slashes followed by the comment text, as shown below

<script language=javascript><!-- JavaScript program // Annotation text --></script>

The red part is the comment! The comment text is only for programmers to read and use, and will not affect the operation of the program. In addition, there is another kind of annotation that can be used in a larger range, which is presented through the wording of /* annotation content*/, and the text enclosed in /* and */ will become annotations.

<script language=javascript>
<!--
/*

</script>
