JSON
Definition.
JSON: JavaScript Object Notation, an open standard file format and data interchange format that uses human-readable text to store and transmit data objects.
In Practice
This is the format every REST API I build speaks — a Django REST Framework backend serializes to JSON, and a Flutter or Next.js frontend deserializes it back into typed objects on the other end.
