F#

let product arr =
    arr |> Array.reduce (*)

I probably wouldn't define a separate function for this in actual code.

 

Does F# require you to name the arr parameter explicitly or can you simply do the following:

let product = Array.reduce (*)

I've been curious about F# for some time but haven't really done a deep dive.

Yes, you can do that in F#. (You probably know this, but for the sake of onlookers) it is called point-free notation. It can be handy for small functions like this. But I noticed when I use it too much, my code can become hard to understand.

Especially for code examples, I rarely use it because it can confuse readers.
