Why JSON Is the Glue Holding Modern Software Together

What this episode covers

In episode 11 of The Programming Languages Podcast, Lucas and Luna dive into JSON — the unglamorous data format that quietly powers everything from REST APIs to machine learning pipelines. They unpack why JSON won the format wars, how it broke XML's grip, and where its limits start to show (no types, no comments, no streaming). Lucas digs into the recent IETF RFC 9427 updates that finally standardized JSON parsing rules, and they debate whether newer contenders like MessagePack or Protobuf will ever dethrone it. If you've ever copied JSON between services, you'll see it differently after this one. #JSON #RESTfulAPIs #DataFormats #SoftwareEngineering #Technology #FexingoBusiness #BusinessPodcast #IETF #RFC9427 #MessagePack #Protobuf #XML #API #WebDevelopment #Ecosystem #DouglasCrockford #RFC4627 #Serialization Keep every episode free: buymeacoffee.com/fexingo
