Benchmark: Reduce Object vs Map

Script Preparation code:

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

Tests:

Reusing object
Object.entries(data).reduce((acc, [k, v]) => { acc[k] = v.toString(); return acc; }, {});
Creating new object
Object.entries(data).reduce((acc, [k, v]) => ({ ...acc, [k]: v.toString() }), {});
Using map
Object.entries(data).reduce((acc, [k, v]) => { acc.set(k,v) return acc; }, new Map());
