TypeScript is language that allows you to work like that. You may use as many and as few types as you need at any given stage of development.

As you start adding types to your working program compiler debugs your program for you finding various corner cases.

This motivates you to add more types.

Yea, it is indeed how I use typescript, but I do not really like javascript much. Typescript does make it better though. I wish other, nicer languages had this.
