Understanding JavaScript's Call Stack: A Fundamental Concept

JavaScript is a single-threaded language that can only perform one operation at a time. To manage this execution, the Call Stack plays a crucial role. It's a data structure that keeps track of function calls and their order of execution.

Think of it like a stack of plates in the kitchen – when you add a new plate (function), it goes on top, and when it's done, you remove it from the top to make room for another one. The Call Stack works similarly, pushing and popping functions as they're called and finished.

This fundamental concept is essential for JavaScript developers to understand how their code runs and what happens behind the scenes. It's a "Last In, First Out" (LIFO) structure that ensures functions are executed in the correct order and control is returned once each function completes.
