About seven years ago I built a terminal React renderer in JS. It allowed you to craft very powerful UIs in a few lines of code. It supported out of the box scrolling, text wrap, text alignment, and even a crud version of CSS styles.

So why do I say that? Well, I reopened the repository and I'm in the process of upgrading it to my today's standards. It's very interesting to see the difference choices I make today vs seven years ago - and how many of them are enabled by Typescript.
