Did all you Javascript devs intuitively understand typing before using flow/typescript? If not how did you go about learning to type JS? Could you link the resource you used?

Every time I read code written in typescript / flow, even though after googling the type syntax of respective tool/language and then understanding why they were used like they were makes sense, it's very difficult for me to think how I could use them from scratch in my own projects.

How does that intuition of types and the blend of implementation with syntax come ?
