Never use a dependency that you could replace with an afternoon of programming

Your example is more apt than intended: That's not valid json, which only allows string keys. If you use a library it'll either barf now or later when they fix it, so if you're forced to work with an API like that and can't change it, a custom parser is really the only way to go.

Well the good libraries have option flags that will allow you to handle JSON as found in the wild.

That's not JSON, though. It's absolutely something else. Maybe a JS snippet. Maybe YAML. Definitely not JSON, though.

(Some JSON libraries do have option flags, but usually it's about whether, during deserializing into a known type, unknown fields are an error or silently ignored. Or whether C-style comments are an error or considered as whitespace.)

It may not be JSON but it’s out there in the wild. A lot.

Let’s say I’m scraping a website. I can:

1) complain to the owner that “it’s not JSON”.

2) write a parser for a syntax that has no spec, (it’s not JSON, but it sure looks an awful lot like JSON with unquoted keys.)

3) Set ALLOW_UNQUOTED_FIELD_NAMES to true in the Jackson library.

While acceptable, also misleading: JS only does string keys, but unlike JSON it'll convert whatever it's given into strings. Not a problem most of the time, since it'll do the same conversion for both accessing and setting, but good to be aware of if you're doing something like iterating Object.keys()

I use https://jsonformatter.org/json-parser sometime to parse json and to validate.
