The "set up and run a webserver" step is missing

[meggsOmatic]

The first page of the "Beginner" section ends with this sidebar:

If you intend to use your WASM module in a plain HTML website, you'll need to tell wasm-pack to target the web...

In my mind, the most straightforward thing to do with those instructions was to save the example HTML to a local tutorial1_window.html file and directly open it in a browser. That didn't work. Turns out cross-origin restrictions prevent importing ./pkg/tutorial1_window.js when using the file:// protocol.

For some programming backgrounds, it may be a very obvious assumption that "Of course I have already a full web development toolchain set up, which will obviously include a web server serving local static pages, as well as (this thing), (that thing), and (some other thing)".

On the other hand, this is a "Beginner" page, and Rust is primarily a native-code systems-programming language. It's reasonable that some Rust programmers will begin from a background that lacks that assumption.

python -m http.server and http://localhost:8000/tutorial1_window.html was easy once I figured out what the missing piece was. But it took quite some time to figure out what the missing piece was.
