JSON5 is a human-friendly JSON extension that aims to alleviate the limitations of standard JSON. It allows for comments, trailing commas, unquoted keys, single-quoted strings, and multi-line strings. This makes JSON5 files more readable and writable without sacrificing machine-parsability. The library provides robust parsing and serialization, enabling developers to seamlessly work with JSON-like data while enjoying enhanced syntax for configuration files and data interchange. It's perfect for scenarios where readability is crucial.
