Benchmark: Convert Array to Object 2 - Object.fromEntries vs reduce

Script Preparation code:

var data = Array.from(Array(10000).keys()).map(i => ({id: i, value: `val_${i}`}));

Tests:

Object.fromEntries
Object.fromEntries(data.map(obj => [obj.id, obj]));
Reduce (reuse object)
data.reduce((acc, obj) => { acc[obj.id] = obj; return acc; }, {});
Reduce (creating temporary objects)
data.reduce((acc, obj) => ({ ...acc, [obj.id]: obj }), {});
