Convert two objects into one array (JavaScript)

Question

I have 2 JS(json) obects with identical keys:

{"id1" : "some1", "id2" : "some2", "id3" : "some3"}
{"id1" : "another1", "id2" : "another2", "id3" : "another3"}

I need to convert it into

[
    {
        "id" : "id1",
        "some" : "some1",
        "another" : "another1"
    },
    {
        "id" : "id2",
        "some" : "some2",
        "another" : "another2"
    },
    {
        "id" : "id3",
        "some" : "some3",
        "another" : "another3"
    }
]

So, this is the question.
Thanks!

Here you go:

var some = {"id1" : "some1", "id2" : "some2", "id3" : "some3"};
var another = {"id1" : "another1", "id2" : "another2", "id3" : "another3"};

var result = [];
for (var id in some) {
    result.push({
        id: id,
        some: some[id],
        another: another[id]
    });
}

alert(JSON.stringify(result));

@PabloKarlsson Yup, no problem. JavaScript does not evaluate object keys, but does evaluate object values.

can you please elaborate it logic ..i didnt get it .

Avinash Babu Over a year ago

i have added a new key named "name" : "avinash" but it didnt display

Robby Cornelissen Over a year ago

@AvinashBabu What logic? Iterate over the keys of some, create result objects to hold the key and corresponding values from some and another, and add the result objects to an array. Note that the question states that the keys in both objects are identical.

Avinash Babu Over a year ago

how can we add if the keys are different ??

This should work provided each id exists in each hash.

var ids = {"id1" : "some1", "id2" : "some2", "id3" : "some3"};
var ids2 = {"id1" : "another1", "id2" : "another2", "id3" : "another3"};
a= [];
for (var id in ids) {
  a.push({id: id, some:ids[id], another : ids2[id]});
}

An easy way is to double push if you have a little object like that

const ob1 = {
  "id1": "some1",
  "id2": "some2",
  "id3": "some3"
}
const ob2 = {
  "id1": "another1",
  "id2": "another2",
  "id3": "another3"
}
let array = []
array.push(ob1)
array.push(ob2)
console.log(array)
