TIL about the greek question mark
Tell me, can you tell the difference between these two characters?

You need to remember that a lot of those best practices are to cover for the performance issues from misusing loosely typed variables.
The JavaScript engine can compile clean, type-safe code down to be almost as fast as properly compiled code. When you use various features like the loose equals or various object mutations and the like, the engine cannot optimize it, leaving your code much, much slower.
I'll add that to my mountain of reasons for using typescript
Yup! I love TypeScript, and I love the flexibility of JavaScript. With all of the type templates and generics and other black magic TypeScript has, it's pretty easy to even support the crazy stuff like mixins and contextual parameters (if I'm not speaking too loosely while avoiding proper terms!).
A lot of the crazy stuff won't optimize, but at least it goes to show how it's not really tying JavaScript's hands even when requiring TS everywhere.
