Benchmark: Copy properties fixed

Script Preparation code:

var wido = {};
for (var index = 0; index < 100; ++index) {
    wido['a' + index] = index;
}

Tests:

Object.entries + reduce
Object.entries(wido).reduce( (res, [key, value]) => Object.assign(res, { [key]: value }), {}, );
Object.entries + reduce + entry object
Object.entries(wido).reduce( (res, entry) => Object.assign(res, { [entry[0]]: entry[1] }), {}, );
Object.keys
var wido3 = {}; Object.keys(wido).forEach(key => { wido3[key] = wido[key]; });
Object.entries + assignment
var wido4 = {}; Object.entries(wido).forEach(([key, value]) => { wido4[key] = value; });
for + assignmen
var wido5 = {}; for (key in wido) { wido5[key] = wido[key]; }
Object.entries + assignment + entry object
var wido4 = {}; Object.entries(wido).forEach((entry) => { wido4[entry[0]] = entry[1]; });
