Agreed, reduce is for a lot more than just reduce-ing arrays to something smaller (like a number of a string). That's why some languages like Rust and Kotlin call it "fold." That's because you're "folding" something of one data type (like an array) into something of another data type (like a Map in your example). Doesn't mean we've reduced it, we've just changed it into something different!
