Custom Types

Upon completion of this lesson you have officially* become a TypeScript Hero. No longer are you limited to TypeScript’s pre-defined types; you have now learned how to create your own custom types! These include:

  • Enums (both string and numeric)
  • Object types
  • Function types

Furthermore, you learned how to refer to complex types using type aliases. And you even learned to master generics, which are like doubly-custom types. Impressive!
