Programmatically accessing function scope using Chrome DevTools console

by

What is the difference between some named object nested directly within a function and some object contained within a Closure in its function scope?

The object nested directly with the function is a property of the function object. For example, $.Callback has a .length property with value 1, it does have a .prototype property, it does inherit (__proto__) from Function.prototype etc.

The object in the scope is a variable that is accessible from the scope that surrounds the function. See How do JavaScript closures work?

How do I programmatically reference a function scope in the console?

You cannot. Scopes are not programatically accessible. I don’t think the devtools have any helpers to allow this either. See also How do I search through scope variables in Google Chrome Developer Tools?
