Array equality

Benchmark created on

Setup

const cnt = 10
const a = Array.from(new Array(cnt).keys())
const b = Array.from(new Array(cnt).keys()).reverse()
function compare1(a, b) {
  if (a.length !== b.length) return false
  const newA = a.sort()
  const newB = b.sort()
  return newA.join(',') === newB.join(',')
}
function compare2(a, b) {
	return a.length === b.length && new Set(a.concat(b)).size === a.length
}
