If Typescript is the first language in which you've encountered generics, the concept can be quite difficult to understand. We skip the lecture in this lesson and dive straight into a real-world use-case that is guaranteed to help you understand the need for generics.
Handling state with Typescript enums, instead of booleans, is preferred because:
- Enums are more readable
- Enums can have as many states as you need while booleans only have 2
- You only need to keep track of state with 1 variable when using enums
- installing the compiler with Node.js
- auto-watching source files for changes
- fixing code errors found by TypeScript
