What is a call stack in JavaScript?
An example of an AI chatbot conversation about call stacks in JavaScript.
Can you explain what a call stack is in JavaScript?
Sure! A call stack is a data structure that keeps track of function calls in JavaScript. It follows a Last In, First Out (LIFO) order.
How does the call stack work when a function calls another function?
When a function is called, it's added to the top of the call stack. When the function completes, it's removed from the stack, and control returns to the previous function.
Can you give me an example of a call stack in action?
Absolutely! If you have function A calling function B, and then function B calls function C, the call stack will look like this: C on top, then B, then A.
What happens if there is an error in one of the functions?
If an error occurs, the call stack unwinds, and the error is thrown back up the stack until it's caught or reaches the global context.
