JavaScript the Hard Parts: Exploring Recursion in JavaScript

[@williamlucas8474]

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

[@MehranMoalemi]

these type of videos are super useful and amazing, there are few likes or views but I want you to know that you are amazing and we need this, keep working and good job. thank you for every thing.

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

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!
