Sorry, just trying to understand.

Are you saying you invented hot reload? And a dev tools css editor?

I am confused, because the ability to edit code and have the page update instantly exists with Vite, and next.js, and a bunch of other frameworks. It’s janky at times but good enough for most - and your edits are in your repo ready to commit. And browser CSS inspectors are really great. And there’s the React DevTools if you need to see props & component hierarchy.

Can you explain the value add over all these free things we already have?
