Hi Ram,
When we are writing code only for server side means client checkbox is not checked then we have a initialize function available in script include Class code.
This initialize function is actually very useful. Whatever code we write in initialize () function then it will get execute every time when we create an object of script include class.
The initialize() function is basically the constructor for the initialized object.
var objDemo=new DemoScriptIncludeClass();
once we have initialized object objDemo of class DemoScriptIncludeClass as mentioned above then the code written in initialize () will get executed.
I hope this helps to understand the concept.
Private function:
Private function in script include is basically which is not accessible from client side. Private functions should have prefix “ _”. Below is the screenshot for the same:

To use script include servicenow at client side we have to make sure that client callable checkbox in script include interface should be checked and script include class should be extending class ‘AbstractAjaxProcessor’ (glide ajax – through which client script communicate with server-side script).
If my answer helped you in any way, mark answer as helpful and correct.
Thanks and regards,
Megha.
