The syntax of JavaScript is the set of rules that define a correctly structured JavaScript program. JavaScript can be implemented in a webpage using JavaScript statements that are placed within the <script>… </script> HTML tags in a web page. If you are using HTML5 standard then syntax will be like
<script>
alert( "First JavasSript Code");
</script>
If you are using HTML4 or below then use syntax
<script language="javascript" type="text/javascript">
alert( "First JavasSript Code");
</script>
JavaScript Comments
For single line comments use “// ” and for multi-line comments use “/* */”, See below given example …
<script>
// Single line commnets
/*
* Multi line comments line 1
* Multi line comments line 2
*/
</script>
