JavaScript the Hard Parts: Exploring Recursion in JavaScript

During this online workshop recording, Kyle will explore one of the most powerful but often confusing concepts in programming: functions that call themselves. We'll cover how to write recursive functions and how you can return a value out of a recursive call.
We'll cover:
- When to use looping vs. recursion
- How to set up recursive functions
- How you can return a value out of a recursive call

I am very impressed. What an excellent way to teach programming. Every student knew how to step through the call stack and set up the stack frames. I looked at the very first course, and sure enough, the instructors had students learning and going through this process. If this had been done in my JS course, I would not have had to come here. But I am glad I did.

This was so helpful, thank you Codesmith team for recording and uploading this video

[@hroman_codes]

Great video explanation! Best one I have seen so far!

[@jayeshthanvi1115]

can you explain with nested array and object

[@Codesmith]

Hey @jayeshthanvi1115! Recursion is often a great choice when handling nested arrays and objects because you don’t know ahead of time _how many levels_ of nesting there are! Also, you can think of nested arrays and objects as having a _recursive structure_ (i.e., an array containing arrays containing arrays, etc.) - a recursive function mirrors the recursive structure of the data 🤯

@codesmith if you run tail recursive exercise with param 15000 you'll get Maximum call stack size error. Could it be that I am doing something wrong?

[@Codesmith]

So, fun fact on this one - even though tail call recursion has been part of the JavaScript specification since ES6, the majority of browsers have chosen not to implement it. If you’re running these exercises in a browser console, that is likely why it’s not working!
