Benchmark: Checking array equality

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

function generateRandomStrings(count = 1000, length = 32) {
  const chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
  const charLen = chars.length;

  return Array.from({ length: count }, () => {
    let s = '';
    for (let i = 0; i < length; i++) {
      s += chars.charAt(Math.floor(Math.random() * charLen));
    }
    return s;
  });
}


function arraysEqualBySorting(a, b) {
  if (a.length !== b.length) return false;
  return _.isEqual(_.sortBy(a), _.sortBy(b));
}

var first = generateRandomStrings();
var second = generateRandomStrings();

Tests:

With 10000
arraysEqualBySorting(generateRandomStrings(10000, 32), generateRandomStrings(10000, 32))
With 100000
arraysEqualBySorting(generateRandomStrings(100000, 32), generateRandomStrings(100000, 32))
With 100000 and same arrays
var a = generateRandomStrings(100000, 32) arraysEqualBySorting(a, a)
With 100000 and 128 strings
arraysEqualBySorting(generateRandomStrings(100000, 128), generateRandomStrings(100000, 128))
