Panel 1: Bilbo Baggins ponders, “After all… why should I care about the difference between int and String?
Panel 2: Bilbo Baggins is revealed to be an API developer. He continues, “JSON is always String, anyways…”
To whoever does that, I hope that there is a special place in hell where they force you to do type safe API bindings for a JSON API, and every time you use the wrong type for a value, they cave your skull in.

"Hey, it appears to be int most of the time except that one time it has letters."

Rust has perfectly fine tools to deal with such issues, namely enums. Of course that cascades through every bit of related code and is a major pain.
This man has interacted with SAP.
The worst thing is: you can't even put an int in a json file. Only doubles. For most people that is fine, since a double can function as a 32 bit int. But not when you are using 64 bit identifiers or timestamps.
That’s an artifact of JavaScript, not JSON. The JSON spec states that numbers are a sequence of digits with up to one decimal point. Implementations are not obligated to decode numbers as floating point. Go will happily decode into a 64-bit int, or into an arbitrary precision number.
You HAVE to. I am a Rust dev too and I'm telling you, if you don't convert numbers to strings in json, browsers are going to overflow them and you will have incomprehensible bugs. Json can only be trusted when serde is used on both ends
This is understandable in that use case. But it's not everyday that you deal with values in the range of overflows. So I mostly assumed this is fine in that use case.
Relax, it's just JSON. If you wanted to not be stringly-typed, you'd have not used JSON.
(though to be fair, I hate it when people do bullshit types, but they got a point in that you ought to not use JSON in the first place if it matters)
As if I had a choice. Most of the time I'm only on the receiving end, not the sending end. I can't just magically use something else when that something else doesn't exist.
Heck, even when I'm on the sending end, I'd use JSON. Just not bullshit ones. It's not complicated to only have static types, or having discriminant fields
Well, apart from float numbers and booleans, all other types can only be represented by a string in JSON. Date with timezone? String. BigNumber/Decimal? String. Enum? String. Everything is a string in JSON, so why bother?
I got nothing against other types. Just numbers/misleading types.
Although, enum variants shall have a label field for identification if they aren't automatically inferable.
No problem with strings in JSON, until some smart developer you get JSONs from decides to interchangeably use String and number, and maybe a boolean (but only
false
) to show that the value is not set, and of coursenull
for a missing value that was supposed to be optional all along but go figure that it was
