Script Preparation code:
var obj = new Object() var keys = (new Array(10000)).fill(0).map((x, i) => { return i + 1 }) keys.forEach((x) => { obj['prop' + x] = x })
Tests:
For In
for (var key in obj) { console.log(obj[key]); }
Object values
for(let value of Object.values(obj)){ console.log(value); }
Object keys forEach
Object.keys(obj).forEach(key => console.log(obj[key]));
Object entries forEach
Object.entries(obj).forEach(([key, value]) => console.log(key,'->',value));
object values forEach
Object.values(obj).forEach(value => console.log(value));
