<!-- > - HTML

The comment tag is used to insert comments in the source code. Comments are not displayed in the browsers.

‍

You can use comments to explain your code, which can help you when you edit the source code at a later date. This is especially useful if you have a lot of code.

‍CODE:

<script type="text/javascript">
<!--
function displayMsg() {
 alert("Hello World!")
}
// -- >
</script>

‍

Note: The two forward slashes at the end of comment line (//) is the JavaScript comment symbol. This prevents JavaScript from executing the --> tag.
