Pascal’s Triangle in React

code style: prettier

❓ Why does this exist?

I was bored so I recreated Pascal’s triangle in React just for fun. I did not look up any implementations of Pascal’s triangle in JavaScript before making this, the logic is all of my own. I made this in around an hour. This also is definitely not the most efficient JavaScript Pascal’s triangle implementation, far from it ?

As for dependencies, it just uses React, TailwindCSS and I used Vite as my development environment. I also used a useList hook from react-use.

The code isn’t exactly beautiful, as I made this under an hour I didn’t bother commenting or making the code look too clean. The user interface itself works, but there may be some CSS edgecases that haven’t been properly implemented (example: overflow handling). Maybe one day I’ll document the code but probably not.
