If you work in web development, there is almost no chance you have not ever heard about TypeScript — the strictly typed superset of JavaScript. Chances are you even (willingly or not) learned at least the basics of this language. Most of the major frameworks like Angular, React and Vue offer you the ability to write your projects in TS rather than plain old JS. But Angular was the first one to massively adopt it, so, for Angular developers, knowing TS as well as possible is a must.

I won’t be listing the benefits of using TS, or the basics of the language. Instead, I am going to focus on some patterns that often mislead developers writing code in TS, and help everyone utilize the power of static typing better.
