WebAssembly is already available from Javascript for both the browser and the server (Node.js) 🤗

In this case, Wasmer provides a lot of useful packages to interact with WebAssembly modules in Javascript easily.

In this section we will see how to setup both your server-side and browser environments to use WebAssembly, and also how to use WebAssembly modules that interact with the Operating System such as WASI using the different packages that Wasmer offer for Javascript.
