In SharePoint Sites, it has lot of built in controls that can generate the number of dynamic scripts required for site. That enables the user to interact with the browser for some basic client operations.
Open the browser, then navigate to the page and view the source of the page. Then search for “_spPageContentInfo”.
This will show you the four or five lines of JavaScript variables with values. Actually “_spPageContentInfo” is the JavaScript key value pair array variable dynamically generated by the SharePoint OOTB control.
The following table shows you the key value pair of that array.
