    Create and Run a Native WebAssembly Function

    In this introduction, we show a simple WebAssembly function that returns the square root of a number. To create this function we load up WebAssembly Explorer (https://mbebenita.github.io/WasmExplorer/), writing the native WAST code to create and export the function. We compile and download the resulting WebAssembly binary, loading this with the Fetch API and WebAssembly JavaScript API to call the function in the browser.
