I've found in strongly typed systems if I lean heavily on the type system refactoring is a dream. I make the changes I want. Then follow the compiler errors. Most of the time it just works. Rarely does that introduce bugs. However if you use a Typed language without using the type system to enforce the design constraints then the type system just gets in your way. In that case refactoring is just as hard. It's very easy in Type Script to write code that might as well be written in a dynamic language. It often is.
