More FAQs in How JavaScript Handles Nested Function Calls
Each nested call pushes a new frame onto the call stack. The engine runs the top frame, returns its value, and pops it. The previous frame then resumes at the next statement.
Through the scope chain, which is based on where functions are written (lexical scope), not where they are called. The engine looks locally first, then follows outer environment references up the chain.
No. Each function call has its own execution context and its own local variables. Inner functions can only access outer variables through the scope chain or closures, not through the call stack.
