Course of Solving Type Challenges

💸 First lesson available without registration 💸

TypeScript has a very powerful type system. With the TypeChallenges, we can discover and practice these advanced capabilities that will allow you to deeply understand the language's type system. For example:

• Structural Typing
• Infer
• Conditional Typing
• Conditional Typing constraints
• Key remapping
• Mapped types
• Intersectional Types
• Union Types

Although they are not features you will use in your day-to-day work, knowing them is useful for understanding libraries you use like TypeORM, pinia,… In fact, it is especially useful if you are developing libraries or tooling but also if you want to know the ins and outs of the language.

The challenges can be solved in multiple ways. We would love for you to share your solutions in the comments!
