How to find the maximum of three numbers

Written by Paul Hudson    @twostraws

The easiest way to find the maximum of three numbers is to use the max() function twice: once with your first two numbers, and again with your third number and the result of the first call. Here's an example:

let first = 10
let second = 15
let third = 18

let largest = max(max(first, second), third)
