@coja I am the engineer because I forget about Math.max existence

Last one should be // still a student

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).

I'm mostly lost and in over my head

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

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

my $max = $x > $y ? $x : $y;
