What does it do?

You can:

• generate sudokus on-the fly (no static input is used, generator is not very fast)
• play sudoku (state for current game is stored locally)

Problems

This was my first project in both React and TypeScript, so there are MANY quirks.

Code problems:

• This uses quite a lot of class instances in state and prop values. At the time of writing I did not realize that this is an anti-pattern.
• Aiming to "keep it simple", this does not use a global store, also no reducers in places where it would make sense
• As a result: A lot of object-cloning and complicated stateful components
• Does not use create-react-app, quirky build setup and no HMR

App problems:

• Generator cannot reliably produce puzzles with less than 24 hints
• Generator is often slow
• No lazy loading
• UI is not very pretty, no dark mode
