In plain words
33 line React is a lightweight React implementation created in 2020. It demonstrates core React functionality in minimal code, making it useful for developers who want to understand how React works under the hood or need a bare-bones version for educational purposes. The project is designed for programmers interested in learning React's fundamentals through a simplified codebase rather than engaging with the full framework.

Thoughts on reading through the hacker news response . 96 line version with JSX compiler. React you pass in a function that takes state and returns a virtual DOM (just a tree of plain ol' js objects) it renders that virtual DOM as a real DOM in the browser if you change the state, it runs the function again, this returns a new virtual DOM it efficiently updates the real DOM so that it matches the new virtual DOM It also does a load of other crap as well, but we're going to ignore that. In this post, I'm going to make the smallest React-like thing that can do the above. It's very mithril influenced. Here are sample applications: calendar picker , snake that use the library .

https://github.com/OlexG/finclaw ^ repo if anyone wants to contribute. I realized that sometimes I'm pretty good at making random guesses about the future. (I.E, I think OpenAI will beat Anthropic in the short term, etc...) However, I'm bad at converting these guesses into actual market plays I can profit from. As such, I wanted to make a tool that connects to the right APIs and launches a swarm of agent experts to generate related plays based on your prediction. The very first super shitty V0 MPV just has Polymarket/Kalshi bets, but I will be adding a more complex…
