Benchmark: Sequencer - MeasureThat.net

HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

const key = 'id';
const sequence = ['foo', 'bar', 'baz', 'qux', 'quz'];

const objects = [{ id: 'baz' }, null, { id: 'foo' }, {id: 'quz}];
sequencer(key, sequence, objects)

Tests:

for loops
function sequencer(key, sequence, objects) { const keyMap = new Map(); for (const o of objects) { if (o != null) { const mapKey = o[key]; keyMap.set(mapKey, o); } } const result = Array(sequence.length); for (let i = 0; i < sequence.length; i += 1) { result[i] = keyMap.get(sequence[i]) ?? null; } return result; }
Array methods
function sequencer(key, sequence, objects) { const keyMap = objects.reduce((acc, o) => { if (o == null) { return acc; } const mapKey = o[key]; acc.set(mapKey, o); return acc; }, new Map()); return sequence.map((k) => { const value = keyMap.get(k); return value ?? null; }); }
