Benchmark: intersect v2da - MeasureThat.net

Script Preparation code:

Array.prototype.shuffle = function() {
  let m = this.length, i;
  while (m) {
    i = (Math.random() * m--) >>> 0;
    [this[m], this[i]] = [this[i], this[m]]
  }
  return this;
};

var watched = [];
for(let i = 0; i < 100000; i++){watched.push({programId:Math.random()});}

var ignored = [...watched];
ignored.shuffle();
ignored = ignored.slice(50000, 59000);

Tests:

some
let i = 0; watched.filter(wObj => { return !ignored.some((iObj, ndx) => { i++; return iObj.programId === wObj.programId; }); }); console.log(i);
some; pop and swap
let i = 0; watched.filter(wObj => !ignored.some((iObj, ndx) => { if (iObj.programId === wObj.programId) { i++; ignored[ndx].programId = ignored.pop().programId; return true; } return false; }) ); console.log(i);
