Script Preparation code:

var obj = {};
for (let i = 0; i < 1000; i++) {
    const randomNum = Math.floor(Math.random() * 4);
    obj[i.toString()] =
        randomNum === 0 ? "undefined" : randomNum === 1 ? false : true;
}

Tests:

Lodash pickBy
_.pickBy(obj);
Native Filter
function pickBy(object) { const obj = {}; for (const key in object) { if (object[key]) { obj[key] = object[key]; } } return obj; } pickBy(obj)
ES6 Filter
Object.keys(obj).filter(key => { if (obj[key]) return obj[key] })
