Does JavaScript sort dictionaries automatically?

Here's an issue we're facing: when the ajax script receives a dictionary from the server, the order changes:

The server sent this:

{753: 'Wraith', 752: 'Phantom Extended', 751: 'Phantom', 750: 'Ghost Extended', 749: 'Ghost', 748: 'Dawn', 747: 'Cullinan', 746: 'Black Badge'}

However, the client receives this:

{746: "Black Badge", 747: "Cullinan", 748: "Dawn", 749: "Ghost", 750: "Ghost Extended", 751: "Phantom", 752: "Phantom Extended", 753: "Wraith"}

JavaScript:

$.ajax({
    method: 'GET',
    url: request_url,
    success: function(data){
        console.log(data.response_models);
        ...

Additionally, the server is running on Django.

Any assistance would be greatly appreciated. Thank you!

Answer №1

When dealing with objects that have properties functioning as "indexes" (numeric strings within the range 0 to 2^32-1), these properties will always be listed in sorted numeric order during enumeration. This ordering cannot be altered.

For a more sensible data format, consider having your server application return data as an array of number-string pairs or an array of objects like {id, value}. If altering the server-side response is not feasible, you can convert the object to the desired format on the client side. Here's an example:

response = {753: 'Wraith', 752: 'Phantom Extended', 751: 'Phantom', 750: 'Ghost Extended', 749: 'Ghost', 748: 'Dawn', 747: 'Cullinan', 746: 'Black Badge'}

dataToDisplay = Object.entries(response).sort(
    ([key1, val1], [key2, val2]) =>
        val1.localeCompare(val2))

console.log(dataToDisplay)
