Isn’t reduce just aggregation operations such as count, sum, etc? What’s even the alternative there if someone disliked doing aggregation for some reason? What if I anecdotally disliked subtraction?
It’s aggregation in general. It’s the iterator function you can use to implement sum, or count, or both at the same time.
This post is just saying that’s interesting that people dislike is more than say map or filter
Reduce is harder to read. Maps and filters are deeply simple. The problem space a reduce can solve is, I’m pretty sure, strictly larger than both of them. Its generality is its downfall.
I’ll happily use a reduce, but it has to be either as a well named function or immediately stored in a well named variable. If the reduce is complex enough that you can’t name it, that’s a smell to me, reach for a different tool.
With explanations like this, who can blame them 😁
