How to push to associative array in javascript?

I know this question was asked many times but i cant get it to work properly as i need. In a node.js ws i push objects into some array like this:

var arr = [];
arr.push({"name": "someName", "id": 12345});

and at the end i send it as a json in the response. How can i push into the array so ill be able to extract data like this ( in the client side ): ** the ID numbers are unique

var name = dataArr[12345];  //will return 'someName'

Im trying to avoid the need to iterate the whole array to get specific values.

If you want named properties, don't use an Array. Arrays are for ordered data structures accessed by index.

Use an Object instead.

var obj = {};
obj['12345'] = "someName";
