Benchmark: Object mapping test

HTML Preparation code:

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

Script Preparation code:

let array = [];
for (i = 0; i < 100; i++) {
    array.push({
        id: i,
        other: "text"
    });
}

let objectsToSet = [];
for (i = 0; i < 100; i++) {
    objectsToSet.push({
        objectId: i,
        object: undefined,
    });
}

Tests:

Map + forEach
const data = new Map(array.map((d) => [d.id, d])); objectsToSet.forEach((obj) => { obj.object = data.get(obj.objectId); });
forEach + forEach
const data = []; array.forEach((d) => data[d.id] = d); objectsToSet.forEach((obj) => { obj.object = data[obj.objectId]; });
