Is it possible to partially describe a string in TypeScript?

Question

Is it possible to partially describe a string in TypeScript?

You can describe possible valid inputs for a string using the string literals in the TypeScript types but I am wondering if you can do something more loose. Like describing the prefix needed on an otherwise ambiguous string
