After using TypeScript there's some features that I'm terrified of that seem counter intuitive. All the following examples produce NO errors and are with every single strict TS option enabled.

1 & 2 are both examples of TS giving you the ability to override the type system. Great power requires great responsibility. If you screw it up then it’s on you.
1 and 2 are not justifiable at all. They can both be strictly enforced. There is already an escape hatch and it's called 'any'.
