Convert multiple objects in array into an array

Question

I want to convert this:

var x = [{ order_id: 10,
           product_id: 5,
           product_after_price: 50 },
         { order_id: 10,
           product_id: 6,
           product_after_price: 50 }]

Into this:

[[10, 5, 50], [10, 6, 50]]

I tried .map() function but it just doesn't work. Any help would be appreciated, thank you!

Answer 1

Without considering order, simply use map

arr.map( s => Object.values(s) )

But you need to specify the order first

var order = ["order_id", "product_id", "product_after_price"];

then use map

var output = arr.map( function(item){
   return order.reduce( function(a,c){
      a.push( item[c] );
     return a;
   }, []);
})

Demo

var order = ["order_id", "product_id", "product_after_price"];
var x = [{
    order_id: 10,
    product_id: 5,
    product_after_price: 50
  },
  {
    order_id: 10,
    product_id: 6,
    product_after_price: 50
  }
];
var output = x.map(function(item) {
  return order.reduce(function(a, c) {
    a.push( item[c] );
    return a;
  }, []);
});

console.log(output);
