Tests:

  • Object.values

     
    const testArray = [];
    Object.values(window.parentObj).forEach(v => {
        testArray.push(v);    
    });

  • Object.keys.map

     
    const testArray = [];
    Object.keys(window.parentObj).map(k => {
        testArray.push(window.parentObj[k]);    
    });
