Benchmark: Object.fromEntries vs reduce with keys as indexes

Script Preparation code:

var data = [{
    test: 1,
    test: 1,
    test: 1,
    test: 1,
    test: 1,
    test: 1
}, {
    test: 1,
    test: 1,
    test: 1,
    test: 1,
    test: 1,
    test: 1
}, {
    test: 1,
    test: 1,
    test: 1,
    test: 1,
    test: 1,
    test: 1
}, {
    test: 1,
    test: 1,
    test: 1,
    test: 1,
    test: 1,
    test: 1
}, {
    test: 1,
    test: 1,
    test: 1,
    test: 1,
    test: 1,
    test: 1
}, {
    test: 1,
    test: 1,
    test: 1,
    test: 1,
    test: 1,
    test: 1
}]

Tests:

With reduce with an id inside the object
data.reduce((previousKeys, actualKey, indexKey) => { previousKeys[ indexKey ] = { id: indexKey, order: indexKey, ...actualKey }; return previousKeys; }, {});
with Object.fromEntries ( array.map( ... ) ) with an id inside the object
Object.fromEntries(data.map((key, value) => [ value, { id: value, ...key } ]));
