Damn right !!

No, but thank God my colleagues understand the complexity difference, and inner working of hashtables, trees and other useful data structures. Knowledge is power...

@meros but knowledge is not easy to show in front of other people 😂

@meros how so? I'm trying to learn so I can pass a technical interview but I never use it in my own apps and don't see much of a point, guess never did any work at a scale where it matters.

All I know is if you have a large list, that you need to search repeatedly, it will be insanely slow, use hashmap or a tree

@allanx2000 complexity and solution scalability on a system level is far more complex than choosing between a list or hashtable, but being proficient in the basics helps a lot.
