Show HN: I built a web app for learning Vim from the browser as a 17-year-old

After my own experiences with learning Vim, I wanted to skip the frustrating process of configuring a new tool before even learning how to use it. In an attempt to solve this problem, I started working on Vim Ninja, a web app that would allow developers to learn Vim through interactive lessons in the browser. It’s been a couple of months, and I’m proud to say that I’ve finally released https://VimNinja.com!

Check out a demo of the app here: https://youtu.be/reukQHKqMZE.

On the technical side of things, I used SvelteKit to build the entire app and Tailwind, which turned out to be an amazing decision. I actually really like SvelteKit’s filesystem-based router as well as Svelte’s brevity, and Tailwind actually makes styling a fun task for me. I’m using CodeMirror 6 as a base for Vim Ninja’s code editor, and I really prefer it over more feature-packed alternatives like the Monaco Editor, which is what I started out with but soon abandoned due to its worse performance when compared to alternatives like CM6 and the sheer amount of bells and whistles that I just didn’t need.

Interesting. I'd assumed you would have gone with a WASM implementation of Vim, since perhaps more advanced tutorials might need more than just vim-like keybindings. Though I suppose that wouldn't come up until much later.
