Benchmark: reduce vs map + fromEntries vs reduce spread

Script Preparation code:

var data = { ...Array.from(Array(10000).keys()) };

Tests:

reduce
Object.entries(data).reduce((acc, [k, v]) => { acc[k] = v.toString(); return acc; }, {});
map + fromEntries
Object.fromEntries(Object.entries(data).map(([k, v]) => ([k, v.toString()])));
reduce spread
Object.entries(data).reduce((acc, [k, v]) => ({ ...acc, [k]: v.toString(), }), {});
