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.

Everything works fine when test.wasm is served, but when locally referenced, the test file is not able to be acquired.

Are you running a local server to serve the files? This is necessary for the loading to work.
