Benchmark: Set.has VS Array.some

Tests:

Set.has multiple
const oldData = Array.from({ length: 500 }, (x, i) => ({ id: String(i), x: 0, y: 0 })); const newData = Array.from({ length: 50 }, (x, i) => ({ id: String(i * 10), x: 1, y: 1 })); const oldDataSet = new Set(oldData.map((od) => od.id)); for (const nd of newData) { const has = oldDataSet.has(nd.id); }
Array.some multiple
const oldData = Array.from({ length: 500 }, (x, i) => ({ id: String(i), x: 0, y: 0 })); const newData = Array.from({ length: 50 }, (x, i) => ({ id: String(i * 10), x: 1, y: 1 })); for (const nd of newData) { const has = oldData.some((od) => od.id === nd.id); }
Set.has single
const oldData = Array.from({ length: 500 }, (x, i) => ({ id: String(i), x: 0, y: 0 })); const findId = "450"; const oldDataSet = new Set(oldData.map((od) => od.id)); const has = oldDataSet.has(findId);
Array.some single
const oldData = Array.from({ length: 500 }, (x, i) => ({ id: String(i), x: 0, y: 0 })); const findId = "450"; const has = oldData.some((od) => od.id === findId);
