a JavaScript and Python script that has subprograms nested three deep and in which each nested subprogram references variables defined in all of its enclosing subprograms and also has variables used to hide at least 1 variable from a non-local function.

In a language that allows nested subprograms, the programming language has to choose a referencing environment for the executing the passed subprogram when a subprogram is passed as a parameter.  Which of the following is NOT a choice?     deep binding     shallow binding     ad hoc binding     just in time binding

I need help with this racket pl question

Which of these two types of references to subprograms, variables, and objects in code is superior: fully qualified references or unqualified references? An explanation of the issues that arise with C's basic encapsulation and the influence that this has on C++.
