Great. What data structures we will need to know in 2021? I want to prepare myself!

  1. Arrays.

Prepare yourself well 😆

The same ones you needed to know in 2020. These "in 2020" posts are nothing but click-bait in my opinion. Surprised to see one working so well in February. Maybe we should start flooding the site again.

I read this article because Emma knows how to write articles. If it was written by someone else, I may have not.

So you too are judging a book by its cover -- thanks for the validation \s

It won't be invented until later this year, but "Abstract inverted hash-heaps" and going to become very popular.

I think graphs are incredibly valuable because of the amount of insight they can reveal within datasets. Dictionaries can also be a very powerful tool from my (pretty basic) studies of machine learning, along with hashing functions (although that's technically getting into algorithms). I still don't know what to make of the blockchain and if there is any value in learning it, so I suppose I will learn it and report back!
