You’ve used it, you know it. Given a series of numbers, it returns you the biggest one. Simple. Easy. Definitely not blog post worthy.

Syntax

Math.max([value1[, value2[, ...]]])

Usage

var x = Math.max(1, 2, 3); // 3

Spooky Stuff

Oh… You’re still here?

Huh? What happens if you pass some weird stuff to Math.max()? … oh, I mean… we could try some stuff:

	// This isn't spooky, this makes sense!
	Math.max('apple'); // NaN

	// One bad apple spoils the whole bunch...
	Math.max(1, 2, 'apple'); // NaN

	// but wait, JavaScript don't give a crap
	// as long as it can implicitly convert stuff!
	Math.max(1, 2, '3'); // 3

	// but wait, maybe it does care...? If it is
	// in an array??
	Math.max([1, '2', 3]); // NaN

	// Spread operator to the rescue! Now it works
	Math.max(...[1, '2', 3]); // 3

	// F**K...
	Math.max(...[]); // -Infinity

	// Ok seriously just stop
	Math.max([]); // 0

	// WHAT
	Math.max(); // -Infinity

	// I'm going to go home
	Math.max(null); // 0

	// Goodbye, cruel world
	Math.max(undefined); // NaN
