This is the crux of the debate. If you work on CRUD apps, you basically need to know hash maps, and lists, but getting better at SQL and writing clean code is good. But there are many areas where writing the right code vs the wrong code really matters. I was writing something the other day where one small in loop operation was the difference betweeen a method running in miliseconds and minutes. Or choose the right data structure can simplify a feature into 1/10th the code and makes it run 100x better than the wrong one.

This happens to me too it just happens roughly 100x less than me needing to know how to test properly.

It's never the other day it's 10x a day, every day.

So, OP is still correct.
