clamp.js

// Base on https://gist.github.com/kujon/2781489

const clamp = (val, min, max) => {
  const realMin = max > min ? min : max
  const realMax = max > min ? max : min

  return Math.max(realMin, Math.min(realMax, val))
}

range.js

// Basic
// Array.range(12) -> [ 0, 1, 2, 3, ..., 11 ]
Array.range = length => [ ...Array(length).keys() ]

// With specific range
// Array.range(1, 12) -> [ 1, 2, 3, ..., 11 ]
Array.range = [ ...Array(to - from).keys() ].map(v => from + v)

// Another way
Array.range = (from, to) => Array.from({ length: to - from }, (v, idx) => idx + from)
