TypeScript: From Zero to Hero

Learn to develop maintainable JavaScript applications with TypeScript

Learn to develop maintainable JavaScript applications with TypeScript.
We develop ever larger JavaScript applications today. Unfortunately this language is not well-suited for this purpose. That's why we use TypeScript. TypeScript helps by expanding the JavaScript syntax with a type system. As a result, you can detect errors earlier and enjoy better tooling support. This all leads to higher efficiency and code quality.
In this training you start by learning the basics of TypeScript, including primitive types and functions. Then you'll be introduced to more advanced concepts, like literal types, interfaces, and generics. In the end you will master the principle of structural typing with mapped types and conditional types.
There is plenty of time to practice, as you will implement these concepts in an application you build from the ground up.
Did you know that:
- false === true is a compile error?
- interfaces don't exist in JavaScript?
- public and private are a myth?
- a class can implement another class?
- an interface can extend a class?
- defining a class does two things?
- TypeScript is not a typesafe language?
- there exists a type called never?
- TypeS…
