The WebAssembly Stack, encompassing Rust, AssemblyScript, and WebAssembly itself, empowers developers to build high-performance, secure, and portable applications that run seamlessly in browsers and beyond. Leveraging the strengths of systems languages like Rust and TypeScript-inspired AssemblyScript, this stack enables near-native execution speeds, strong memory safety, and powerful cross-platform capabilities. The WebAssembly ecosystem is rapidly evolving, offering a rich set of libraries for everything from core runtime to tooling, data storage, UI, and more, making it a premier choice for modern web and cloud-native development.

Here's a breakdown of the WebAssembly Stack into different categories
