JSON5 — modern JSON

In plain words

JSON5 is a data format that extends standard JSON with human-friendly features. It allows developers to write cleaner configuration files and data structures by supporting comments, trailing commas, unquoted keys, and single quotes. The tool is designed for programmers who want more flexibility than traditional JSON while maintaining compatibility with existing tools. JSON5 is available as an open-source project on GitHub for community contributions and development.

  Talanoa▲339

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
