Do you know if there are any good sites to have a look at TypeScript, I’m more confused about just where to go?
I would just start with getting a high-level understanding of what TypeScript is. You don't need to go crazy with understanding every little thing about it. Understand WHY you should use TypeScript. Here are some quick resources I found.
You could also do something a little more structured like following an Angular tutorial. (I am a bit bias to Angular). Angular uses TypeScript and they have some really easy to follow along with tutorials. BUILDING apps has always been the best way for me to learn something new!
