Good point, for those who need to implement a slick compareFunction for numbers, Math.sign is great: [min, num, max].sort((a, b) => Math.sign(a - b))[1] An entirely different alternative is poor man's match: switch (true) { case num > max: return max; case num < min: return min; default: return num; }

Why sign though? I always write my sorts like this. .sort((a, b) => a - b)

  Is there a better way to grab a reference to the subtraction operator?

    I assume you're referring to a point-free reference. Only by defining a `const subtract = (a, b) => a - b;`, which isn't really point-free. Or by using a different language.
