In this chapter, we reviewed advanced tools and an alternate compilation method for WebAssembly. We learned about WABT and Binaryen's role in the WebAssembly development process and the functionality they provide. We compiled a Wasm module with LLVM through the use of the WebAssembly npm package and interacted with the result in the browser. We reviewed some of the WebAssembly tooling available online and created a simple application that uses Web Workers to store Wasm modules in separate threads. Finally, we discussed the upcoming features of WebAssembly and the standardization process. Now that you've gained a greater understanding of WebAssembly, go out there and build something!
