I use 8, but only when I'm operating on unsigned longs.

Yoink.

Actually I've probably been all of these at various times in my career.

here’s another mathematical approach (that has the added benefit of only working when x and y are both positive).

let f denote the linear functional on ℝ^2^ defined by f(1,0) = x and f(0,1) = y (and extend by linearity). then the operator norm || f || is equal to max(x,y).

Why use const max = (x, y) => x > y ? x : y instead of function max(x, y) { return x > y ? x : y } ?

I'm mostly lost and in over my head

I mean.. that's JavaScript. Why would I need a function like that in JavaScript to begin with? And why would I trust my fellow Coworkers to not fuck up the input validation on it? 9 all the way baby

2, but I'm incredibly embarrassed to say that I've had to do 9 before
