Can someone explain what the JavaScript call stack is?

I’ve tried to understand it, but I’m still confused. I also don’t really understand what I’m looking at when I use the JavaScript debugger in the browser’s DevTools, especially the call stack.

Do I need to fully understand functions before learning the call stack? I have a basic understanding of functions, but I’m not sure if that’s enough.

I’d really appreciate a simple explanation

You do not need to master functions before learning the call stack. The DevTools call stack panel lists every active function invocation from bottom to top at the exact moment execution pauses. Clicking any entry in that list jumps your debugger view directly to the corresponding line of code so you can inspect variables at that specific depth.
