Script Preparation code:

function dec2hex (dec) {
  return dec < 10
    ? '0' + String(dec)
    : dec.toString(16)
}

function generateId (len) {
  var arr = new Uint8Array((len || 40) / 2)
  window.crypto.getRandomValues(arr)
  return Array.from(arr, dec2hex).join('')
}

var a = []
var b = []
for( let i = 0; i < 1000; i++)
{
  a[i] = generateId(16)

}

Tests:

current xor implementation
const res = _.xor(a, _.xor(a,b))
alternative with Sets
var as = new Set(a) var bs = new Set(b) const res = a .filter((row_id) => bs.has(row_id)) .concat(b.filter((row_id) => !as.has(row_id)))
