Create new array containing objects

Question

I wish to create a new array that contains objects from another Object

This was my try:

var obj =  {
    a:{},
    b:{}
}

var arr = new Array().concat(obj,[]);

Sadly, this is returning an array like this:

Array[1]
0: Object
    a: Object
    b: Object

The desired array, however, should look like this:

Array[2]
    0: Object
        a: Object
    1: Object
        b: Object

How could i achieve that in the shortest possible way, without having to loop the object?

Could you show what the desired end result should look like? — JJJ

Well, the question says you want [{a: obj.a}, {b: obj.b}]. — JJJ

"without having to loop the object" --- what is the technical reason for avoiding explicit loops in the code? — zerkms

Could you explain what problem you're trying to solve by turning the object into an array? This sounds like an XY problem. — Barmar

Here is an example without explicit loops:

var r = Object.keys(obj).map(function(key) {
    var o = {};
    o[key] = this[key];
    return o;
}, obj);
