WebAssembly will have a huge impact on how web developers build their applications, allowing them to gain a lot of performance gains with little effort. It will allow for diversity in terms of application developers, thus allowing them to write web applications in their native language without worrying about learning other frameworks. WebAssembly is not meant to replace Javascript, but to serve as a high-performance language for running complex web applications on the web. The WebAssembly standard is constantly evolving and has a lot of exciting possibilities.

In this chapter, we learned about how Rust can compile down to wasm code and the available tooling that helps ship Rust code on the web. If you want to learn more about WebAssembly, head over to the excellent documentation at: https://developer.mozilla.org/en-US/docs/WebAssembly.

In the next chapter, we will learn a bit about GUI development and how to build desktop applications with Rust.
