The purpose of TypeScript is to provide static types to JavaScript without just turning it into a compile target. TypeScript type system is only confusing because it's modeling real-life ultimately type-less JavaScript code. It's not it's own language with it's own rules -- it lives and dies as JavaScript.

Types can be as simple or complex as needed. Assembler and C have very simple type systems with very few features and can only model very simple situations. Types in TS don't have to be complicated -- blame JavaScript programmers for their crazy designs.
