Benchmark: duplication resolution

Script Preparation code:

var records = new Array(500).fill(null).map(function (_, i) {
  return {toto: i, titi: 'hello'};
});

var keys = ['toto'];

Tests:

M
Object.values(records.reduce(function (acc, record) { const key = keys.map(function (key) { return `${key}: ${record[key]}`; }).join(';'); if (!acc[key]) { acc[key] = record; } return acc; }, {}));
C
records.reduce(function (acc, cur) { const isDup = acc.some(function (item) { var isDup = true; for (const key of keys) { if (item[key] !== cur[key]) { isDup = false; } } return isDup; }); if (!isDup) { acc.push(cur); } return acc; }, []);
