Push new object into a multidimensional array

Say I have this array:

var array = [{'ref1': {'Product': 'Car', 'color': 'Red'}}, {'ref2': {'product': 'velo', 'color': 'red'}}]

I want to add 'price': '8' to only 'ref1'

How can do this properly?

Alex.

Find the index of the ref1 item, then assign the value to the Price parameter.

var array = [{'ref1': {'Product': 'Car', 'color': 'Red'}}, {'ref2': {'product': 'velo', 'color': 'red'}}];
var ref1 = array.filter(item => item == {'ref1': {'Product': 'Car', 'color': 'Red'}})[0];
var index = array.indexOf(ref1);
array[index]['Price'] = 8;

Here is a more dynamic code if you do not know for sure whether the object containing the "ref1" property is always at index 0:

const insert = (idProp, key, value) => {
  var el = array.find(el => el.hasOwnProperty(idProp));
  if (el) { el[idProp][key] = value }
}

then call it via

insert('ref1', 'Price', 8)

You could do something like:

var arr = [{'ref1': {'Product': 'Car', 'color': 'Red'}}, {'ref2': {'product': 'velo', 'color': 'red'}}];

console.log(arr);

arr[0]['ref1'].Price = 8;

console.log(arr);

This is how you do it: array[0]['ref1'].price = 8;

var array = [
  {'ref1': {'Product': 'Car', 'color': 'Red'}}, {'ref2': {'product': 'velo', 'color': 'red'}}]

array[0]['ref1'].price = 8;

console.log(array)

Observation: ref1 has a property Product while ref2 has a property product in lowercase. This may cause you some problems latter.
