ts-is-assignable v0.2.4

ts-simple-type

What is this?

Right now the type checker for Typescript API doesn't expose methods like isAssignableTo. See issue #9879 on the Typescript github repository.

To fill in the gap while this issue is being discussed this library aims to provide the most essential helper functions.
