How to create an external script file?

Rating:

An external script file is a file that is created outside the main HTML document. This file can be invoked in any HTML document with the help of the src attribute of the <script> tag. The code of an external script file can be written in any text editor and must be saved with the .js extension.

The following code will create an external script file:

function myfunc()
{
       //statements
}

When this file is saved as script1.js, the following code can be used to invoke the file in the HTML document:

<script language="JavaScript" src="script1.js">
