Why do I get JavaScript error of "'ej' undefined" while running an application with Syncfusion controls?

Resolving “ej undefined” error while rendering Syncfusion controls

When the referred script files are not in proper order or when the script file, ej.web.all.min.js reference is missing, then the JavaScript error, ej is undefined, occurs when the application with Syncfusion EJWEB controls is run.

Issue Scenario 1:

In the script file reference, the ej.webform.min.js file is placed before the ej.web.all.min.js file.

Issue Scenario 2:

In the script file reference, the ej.web.all.min.js file reference is missing.

The script reference should be in a following order:

ASPX 

<script src="external/jquery-1.10.2.min.js"></script>
<script src="external/jquery.easing.1.3.min.js"></script>
<script src="external/jquery.globalize.min.js"></script>
<script src="external/jsrender.min.js"></script> 
<script src="ej/ej.web.all.min.js"></script> 
<script src="ej/ej.webform.min.js"></script>
