Overview
TypeScript brings static type checking to JavaScript, but this only scratches the surface of what makes TypeScript a truly unique and powerful language. This session will cover some under-utilized and lesser-known TypeScript features. Rob will demonstrate how they can be used to enhance the typing in a simple app, resulting in code that prevents bugs and is easy to work with. By the end of the session, you’ll have a few new tricks up your sleeve to help kick the habit of casting to “any” whenever TypeScript gets in the way.
