Proto vs JSON: When to Use Which (and Why)

Data serialization plays a crucial role in app development, with JSON and Protocol Buffers (Proto) being two commonly used methods. JSON is human-readable and easy to use for public APIs, prototypes, and configurations, while Proto offers faster and smaller data handling, ideal for high-performance applications, microservices, and IoT devices. Choosing between them depends on the specific use case, whether readability or performance is prioritized.
