Benchmark: Object.fromEntries x reduce (correctly using fromEntries - addtl work)

Script Preparation code:

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

Tests:

Object.fromEntries
Object.fromEntries(Object.entries(data).map(([k,v]) => [k+'a',v]));
Reduce (reuse object)
Object.entries(data).reduce((acc, [k, v]) => { acc[k+'a'] = v; return acc; }, {});
Reduce (creating temporary objects)
Object.entries(data).reduce((acc, [k, v]) => ({ ...acc, [k+'a']: v }), {});
