ABUSING C TO IMPLEMENT JSON PARSING WITH STRUCT METHODS

Summary from the TLDR Web Dev newsletter

A memory-safe JSON parser can be made in C using struct methods for a more ergonomic API. The parser represents JSON values using a `json_value` struct with unions for different data types and includes functions for freeing memory and printing the parsed structure. The parsing process combines lexing and parsing into a single pass, handling atoms (numbers, null, true, false), strings, arrays, and objects with helper functions for whitespace skipping and error handling.
