An eample of how you can fully integrate wasm into a webpage. No need for feteching or any of that jazz. What if someone's on a connection with a lot of latency? What if you want to load a wasm app from your hard drive directly, like double-clicking on the HTML file? Whelp, this is that.
Check it out live, here: link
It's a demo of how to integrate the whole shebang into one small HTML file. Get your small .c file compiled into wasm and loaded without any hocus pocus.
