How is the call stack related to execution contexts?
Short interview answer
Calling a function creates and pushes a new execution context. Returning or throwing removes it, resuming the caller. The stack explains synchronous control flow; asynchronous callbacks create later calls rather than leaving the original function frame suspended.
Key takeaway
Explain the underlying mental model clearly, then support it with a concrete example and its trade-offs.
