Scope & Function Stack

The function stack (call stack) is the mechanism that tracks the execution of function calls. Each time a function is called, a new frame is pushed onto the stack; when it returns, the frame is popped. Scope determines which variables are accessible at each point in the call stack, and closures preserve access to variables from outer scopes.
