创建包含对象的新数组

Question

I wish to create a new array that contains objects from another Object 我希望创建一个包含来自另一个Object的对象的新数组

This was my try: 这是我的尝试：

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

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

Sadly, this is returning an array like this: 可悲的是，这是返回一个这样的数组：

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

The desired array, however, should look like this: 但是，所需的数组应如下所示：

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? 我怎么能以最短的方式实现这一点，而不必循环对象？

Answer 1

Here is an example without explicit loops: 这是一个没有显式循环的例子：

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