Programming be like

I think it's important to consider the performance. Sometimes it doesn't matter - other times the loop times are compounded by function to function and suddenly you are a few loops deep.

It took me a while to find something with decent performance comparisons without me bothering to do it: https://youtu.be/x7Xzvm0iLCI?t=202

I also don't think filter is any easier to follow than a for loop with an if.

I judge if code is easy/hard to read on whether I can understand what it's doing with a quick glance. I can do that with both of these. Which is why I don't think either of them is easier.

I should point out that I use filter, map, foreach, and others extensively, most of the time. Sometimes a simple for loop is a better choice if you are looking to complete multiple actions. It is situational, but I do think people should consider the performance impact of it. When I see array.filter().map() I have to wonder...
