There is no JSON in your question, but JavaScript objects. These objects are defined as an unordered collection of properties. Most (all?) ECMAScript implementations keep the order, but I would not count on that.

Instead you could use a Map which guarantees to iterate through the properties in insertion-order. So you can create a new Map and use the link of Dinesh to insert the arrays in order into the Map.
