Hello and welcome to the first issue of This Week in Rust and WebAssembly!

Rust is a systems language pursuing the trifecta: safety, concurrency, and speed.

WebAssembly is designed as a portable target for compilation of high-level languages like C, C++, and Rust, enabling deployment on the web for client and server applications.

This is a weekly summary of its progress and community.
