JavaScript Tutorial #3 – Comments in JavaScript

JavaScript has the support for both single line and multi line comments like C++ or C#.

The single line comment is usually represented by // and the text between // and the end of the line is treated as comment.

The multiline comment is represented by the characters /* and */ and the text between them is a comment and can span across multiple lines.

Below is an example of the JavaScript code with the comments.

<!DOCTYPE html>
    <meta charset="utf-8" />
    <title> Home Page</title>
    <script language="javascript" type="text/javascript">
        document.write('Welcome to JavaScript Tutorial');
        // This is single line comment
        /* This is a multi line comment 1
        This is a multi line comment 2
