it's React. Like there's no big secret. There's there's nothing really complicated. The the reason we picked TypeScript and React is it's very on distribution for the model. So, when we started, you know, building the code base, the model was not as intelligent as it is today, so the language and the framework mattered a lot. Nowadays, you know, it can write whatever, and it can pick up new languages, new frameworks it hasn't seen. But back then, you wanted to use something pretty on distribution. Because of that, I think fairly early we got to the point where the model just wrote 100% of the code. And for us, this happened sometime in October, November last year.
