Difference between 'this' & 'element'

Hi all,

Can anyone explain me the difference between ‘this’ and ‘element’ with an example? Thanks in advance!

In forms Element refers to the current formRun object. THIS can also reference the same formRun object when it is used in the formRun methods. The reference to THIS changes depending on where it has been used.

Example - THIS in terms of form data source(when used in form data source) will actually reference the formDataSource object but the element remains same it always references the formRun object.
