More FAQs in JavaScript Call Stack Basics for Beginners
A LIFO data structure that tracks which function is currently running. Each function call pushes a frame, each return pops one. Only one function runs at a time.
Infinite or very deep recursion. Each call adds a frame to the stack without popping one, until the engine's maximum stack size is exceeded and a RangeError is thrown.
No. JavaScript is single-threaded, so the call stack has one active frame at a time. Other functions must wait for the current one to return.
