Language-Specific Features

WebAssembly provides optimized execution and unique capabilities based on the original language.

Memory Safety

Rust's ownership model ensures memory-safe WebAssembly execution without runtime overhead.

Native Speed

C/C++ code compiles to WebAssembly with near-native execution speed for compute-heavy operations.

JavaScript Interop

JavaScript and TypeScript can be extended with native WebAssembly modules for performance-critical operations.

Future Language Support

Upcoming: Zig

Zig compiler toolchain integration in Q1 2025 will enable lightweight systems programming in WebAssembly.
