JavaScript Syntax and IDE

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
