Add new object to another object's object

var obj = {}

obj.cats = {'name': 'Milo', 'age': 3} // first item

Object.assign(obj.cats, {'name': 'Simba', 'age': 2}) // add new item to obj.cats

console.log(obj) // result one item in obj.cats (Simba)

How can I add to the obj.cats here? All solutions I try they override cats

Wanted result:

obj {
 cats : {
     {'name': 'Milo', 'age': 3},
     {'name': 'Simba', 'age': 2}
 }
}

Your wanted result is not valid, you can try with the object key:

var obj = {}

obj.cats = {1:{'name': 'Milo', 'age': 3}} // first item

Object.assign(obj.cats, {2:{'name': 'Simba', 'age': 2}}) // add new item to obj.cats

console.log(obj) // result one item in obj.cats (Simba)

You can use an array of objects:

var obj = {}

obj.cats = [{name: 'Milo', age: 3}] // first item

obj.cats.push({name: 'Simba', age: 2}) // add new item to obj.cats

console.log(obj) // result two items in obj.cats (Milo & Simba)
