Yeah, and it's not like I didn't know how to do the stuff I was doing with a switch, I just don't like switches because I've forgotten to add break statements and had code that appeared correct but actually a month down the line. I've also seen other people make the same mistakes. ifs, in my opinion at least, are a bit harder to screw up, so I will always prefer them.

But I agree, algorithmic complexity is generally the only thing I focus on, and even then it's almost always a case of "will that actually matter?" If I know that `n` is never going to be more than like `10`, I might not bother trying to optimize an O(n^2) operation.

What I feel often gets ignored in these conversations is latency; people obsess over some "optimization" they learned in college a decade ago, and ignore the 200 HTTP or Redis calls being made ten lines below, despite the fact that the latter will have a substantially higher impact on performance.
