JSX vs TSX in React project

I use in my project by TSX files and in all examples in Mosh’s course written in JSX or JS. And there is different syntax. Any advises?

I’d just follow the course in JavaScript. I know TypeScript is a superset of JavaScript, but, for me, I’d remember more if the video and my code matched.

But then, I’ve never done react, so, weigh my words carefully.

I suggest use the JSX first. Typescript need a very good understanding of interface and data type.
