Pushing an object to an empty array returns the length of array and not the array

I have the following code:

var obj = {
    "entry": [
          {
            "obj1": "data1",
            "obj2": "data2",
            "obj3": "data3",
            "obj4": "data4"
          }
        ],
        "resourceType": "Bundle",
        "total": 100,
        "type": "searchset"
    }

var arr = [];

var keys = arr.push(obj);

This returns me a number instead of the array with objects. Why is that?

What do you mean a number? Where are you seeing that? – Taplar Jan 08 '20 at 20:00

because `push` returns the new length of the array. – Nina Scholz Jan 08 '20 at 20:00
Because that is how the `push` function is defined... – Heretic Monkey Jan 08 '20 at 20:00
