Basic JavaScript: Record Collection problem

Hello guys, I am new at programming and I’m trying to understand how Complex Data and Algorithms work. I’ve seen the solution for this particular question it and I understand most of it but I wanna ask if there are some good resources that would help me learn more about this topic. I see a lot of people have problems with this, so I’m wondering how did the rest of you learn this :slight_smile: ?

I’m a big fan of Kahn Academy for understanding new/difficult/obscure learning. That included algorithms (from a computer science perspective) and complex data.

Thank you! I will check it out! :slight_smile:
