The Lies We Tell Ourselves Using TypeScript
How safe is TypeScript's type safety? How much can you trust your statically typed code? Can you even consider TypeScript's type system "strong"? In this talk, we look at situations where TypeScript fails badly and learn why things have to be that way.

How to make our CLIs safer with types?
In this talk, we will explore the various issues encountered when building JavaScript CLIs, and demonstrate how TypeScript can address them and help us make our applications safer.

By the end of this talk, you'll understand how to abstract runtime validations type behind easy-to-use interfaces, and have all the tools you need to bring those benefits into your own CLIs at little cost - whether they are open-source projects, or internal tools.
