<ul data-eligibleForWebStory="false">The Call Stack is a key concept in programming, acting as a LIFO data structure that tracks the currently executing functions.Functions are pushed onto the Call Stack when called and popped off once they finish executing, ensuring the correct order of execution.The Call Stack aids in function execution order, error handling by providing traces, and memory management by storing context for each function call.Understanding the Call Stack is crucial for debugging, preventing issues like Stack Overflow, and effectively managing function calls in a program.
