How to make a JSON array correctly?

Question

JSON

There is a task to compose a JSON in which an array of goods is transmitted in the form of a GUID and their quantity, they sent me a technical specification in which they want to see it like this:
{
"items": {1234: 1, 4321: 1}
}
I think that it would be correct to compose a two-dimensional an array of the form:
{
"items":
}
At least because in the future, in addition to GUID and quantity, other parameters can be passed and therefore they cannot be passed as a key:value pair . And according to the meaning of the GUID, this is exactly what the value is, and not the key. But the compilers of the TK insist. I thought, what if I'm wrong, I take it to your court.

Answer 1

The array in this case is much worse for the same reasons that you described. 10 parameters will be added - and dick you will understand what it means. + this does not provide uniqueness, makes it difficult to search (full enumeration if you parse directly into arrays and not into a dictionary / associative array / map).
The solution in the TK is also not nice (problems with the extension, yes), but yours is no better either.
My version, which is at least closer to the TK:

{
"items": {
   1234: {
      "count":1
   }
}
}

If you really don’t want to make a GUID a key (although it’s not clear why - it’s unique) - then you can do this:

{
"items": [
   {
      "guid":1234,
      "count":1
   }
]
}
