This could be anything from some specific technologies/tools, data structures, design patterns, programming paradigms to advanced concepts like Machine learning, Neural networks, AI, etc.
Which concept took you the longest to grasp?

Looking through a multi dimensional array in visual basic was a serious headache at the time for me
As a person with a graphic designer background, so without mathematical, scientific or logical background, while I taught myself how to code, what took me the longest was to understand the programming logic.
When you've finished learning the basics of basics (types, loops, variables,...) and you try to actually use them. At first it took me more than 3 hours to finish one simple exercise on codewars but when I understood the logic, it took me less than 5 minutes, the difference was huge.
It took me YEARS to understand and use Redux correctly. There were times I thought this career wasn't for me because I couldn't understand and use this "simple" library.
As I've heard, most have struggled with it.. Have you tried Context API, btw?
recursion!
still struggling xD
For me personally, Redux was a concept really hard to understand and also I didn't understand why it exists. I mean there's better and easier ways to handle state in my opinion back then.
Recursion!!
Mainly because every time I solve a recursion problem I focused more on how its working instead of how to work with it. But Gladly, I have passed that phase but it did take a very long time :)
I'd say either pointers or rxjs Observables.
Lens in Haskell. I still have trouble with them.
I guess Dynamic Programming is the one that took me so much time, I was reading about it from second last year of my high-school but I was only able to do it on the freshman year of my college; my first submission to a DP problem in a live contest, was worth all the patience.
Recursion and pointers.
Probably states in react lol
Some of them were(please don't judge me as I am only a 13 guy learning to program in his spare time):
What I still have problems with:
Try/Catch blocks. Admittedly, I'm still shaky on them. At this point, I just consider them a code smell and avoid writing code that throws exceptions.
Model Factories, TDD
