 creates a new stack frame containing the local execution context of
 that function and pushes it onto the call stack. When that function
 returns, its stack frame is popped from the call stack, leaving the
 interpreter to continue at the next instruction in the stack frame
 from which the function was called. Because functions can call
 functions which call functions and so on in a nearly limitless
 sequence, there can be a number of stack frames in existence at any
