Might I interest you in the following ones? 😄

1. Build your own Uber-for-X app: This is a good way to learn JavaScript and Web sockets
2. Build a social audio chat application: A nice way to understand how WebRTC works

I implemented these projects using regular JavaScript with JSDoc comments for type annotations and function signature. I think it would be a super fun exercise to implement them using React / TypeScript.

Hopefully you like the project ideas to give them a shot! Feel free to ask me in-case you have any questions!
