On the other side of this point, I've used typescript and converted a major project to use it and it was fairly simple. The main thing you should start with for low hanging fruit is database queries. Make sure your database query functions are typed and it'll make the rest of your code much easier to write even if the rest isn't in typescript. Start getting types into the places where the data is coming from. The source of the data.
