Loading external javascript files in web page

External java script files will be included into web page by using <script> tag. 

Here is the example of including external java script file in web page. 

<script src="Cmmon.js" type="text/javascript"></script> 

Script tag should be closed properly. The following example is wrong way of including external java script files. 

<script src="Cmmon.js" type="text/javascript" />

With the above statement only one javascript file will be loaded into page, when you try to load multiple java script files.
