Builds the AST (Abstract Syntax Tree) of a JSON string.
The good #
- It works.
- It is battle tested.
- It could be worse (like not having anything at all).
The bad #
- Types are flimsy
- Algorithms are not a jewel of modern programming.
- I ported this library to use only one feature.
The ugly #
- I would re-write the whole thing if I had any serious interest in this.
