The Ultimate Guide to JavaScript Collections

🧠 Learn about how JavaScript has 4 built-in data structures, and 3 conceptual collections you can make with them: Array, Object, Set, Map, Stack, Queue, Deque. Knowing which ones are ordered, indexed, key/value pairs or allow only unique items is key to solving problems in the simplest way! 💡

Thanks for the helpful video! 👍

I would like to suggest a possible idea for a future video — paradigm of reactive programming in JS. In particular, using the RxJS library.
I ran into some problems trying to comprehend the new approach of reactive programming when developing user interfaces with RxJS, React JS 😧

In any case, thank you very much for your work and enlightening us with new knowledge! 😎
