Benchmark: sorting - MeasureThat.net

Script Preparation code:

ids = [...Array(1000)].map(() => window.crypto.randomUUID());
shuffledData = ids.sort(() => 0.5 - Math.random()).map(id => ({id, value: window.crypto.randomUUID()}));

Tests:

map & find
const sortedData = ids.map(id => shuffledData.find(item => item.id === id));
lookup map using obj
const map = {}; shuffledData.forEach(item => map[item.id] = item); const sortedData = ids.map(id => map[id]);
lookup map using map
const map = new Map(); shuffledData.forEach(item => map.set(item.id, item)); const sortedData = ids.map(id => map.get(id));
