creating object from object in Javascript

I have an object. 

var x = {"id":"asc","metaid":"desc"}

I want to create another object which looks something like this.

[{id: {order:"asc"}},{metaid: {order:"desc"}}]

What I have already tried is this 

const sc1 = [];
var def1 = {}
for (let key of Object.keys(obj)){
def1[key] = {order: obj[key]}
}
sc1.push(def1);

The above code doesn't give required output. Need help with this. Thanks

You can use Array#from

var x = {"id":"asc","metaid":"desc"};
let out = Array.from(Object.entries(x), ([prop, value]) => ({[prop]: {order: value}}));
console.log(out)

Map the entries of the object to return an object with a computed property name:

var x = {"id":"asc","metaid":"desc"};

const result = Object.entries(x)
  .map(([prop, order]) => ({ [prop]: { order } }));
console.log(result);
