JS - how to convert all keys into its values (from objects)

Question

I have something like this (im obtaining it from API, so I cant change it):

{ one: [ { price: ['$10'], weight: ['1000'], color: ['red'] } ],
  two: [ { price: ['$20'], weight: ['2000'], color: ['green'] } ],
  three: [ { price: ['$30'], weight: ['3000'], color: ['blue'] } ] }

And I want to convert all "price", "weight" and "color" keys to its values, to look like this:

{ one: [ '$10', '1000', 'red' ],
  two: [ '$20', '2000', 'green' ],
  three: [ '$30', '3000', 'blue' ] }

Is there any simple way to do this?

Edit: Example fixed
Edit2: Wanted result fixed

Do you mean you want to convert to: [ '$10', 1000, 'red' ]? [ { $10, 1000, red } ] is not valid — Rob M.

You could map use the keys and map the wanted properties form the inner array.

var object = { one: [ { price: ['$10'], weight: ['1000'], color: ['red'] } ], two: [ { price: ['$20'], weight: ['2000'], color: ['green'] } ], three: [ { price: ['$30'], weight: ['3000'], color: ['blue'] } ] };

Object.keys(object).forEach(function (k) {
    object[k] = [ 'price', 'weight', 'color'].map(function (p) {
        return object[k][0][p][0];
    });
});

console.log(object);

.as-console-wrapper { max-height: 100% !important; top: 0; }
