JSON IS SLOWER. HERE ARE ITS 4 FASTER ALTERNATIVES

Summary from the TLDR Web Dev newsletter

JSON's popularity is due to its human-readable format, language-agnostic nature, and support in web browsers and APIs. However, it can introduce performance challenges such as parsing overhead, serialization/deserialization inefficiencies, and lack of support for binary data. This article explores alternatives like Protocol Buffers, MessagePack, BSON, and Avro, and provides optimization strategies such as minimizing data size, using arrays wisely, optimizing number representations, and employing server-side caching. Real-world examples from LinkedIn, Uber, Slack, and Auth0 of these alternatives in practice show improved performance over JSON.
