🆚 JSON vs. WebAssembly

JSON (JavaScript Object Notation) is a lightweight, language-independent data exchange format derived from JavaScript and used to structure and transmit data between systems.

It represents data as key-value pairs and ordered arrays, supports various data types, and is widely used in web APIs, configuration files, and data storage.

WebAssembly (Wasm) is a portable binary instruction format that runs in modern web browsers with near-native performance, enabling frontend coding in languages that were not traditionally used for web interfaces, such as C/C++, C#, and Rust.

It is designed as a low-level compilation target with a compact binary format, fast execution, memory-safe sandboxing, and a stack-based virtual machine. It also integrates with JavaScript to access Web APIs and share memory efficiently.
