How to keep the sequence in javascript Map?

arrays, javascript, sorting

Solution

Objects are unordered in JS. Use an array if order matters.

var myData = [];
myData.push({ "number": 10427, description: "Description 10427" });

Problem

i have myData map as below ``` var myData = new Object(); myData[10427] = "Description 10427"; myData[10504] = "Description 10504"; myData[10419] = "Description 10419"; ``` but now when i iterate over myData, i don't get same sequnce in chrome and IE works fine in firefox. It iterates in ascending order of key ``` for (var key in myData) { alert("key is"+key); } ``` i get the output in ascending order in alert as `10419,10427,10504` How i can make sure to iterate in same order as data as inserted in map?
