var obj = Array.from({ length: 10000 }).map((value, i) => i).reduce((val, v) => { val[v] = v; return val; }, {})

Tests:

lodash.each
_.each(obj, function(v, k) {})
lodash.map
_.map(obj, function(v, k) {})
Object.entries.map
Object.entries(obj).map(function([k, v]) {})
vanilla for-loop w/ Object.entries
const entries = Object.entries(obj); for (let i = 0; i < entries.length; i++) { const [k, v] = entries[i]; }
