Best Practices for TypeScript

  • Avoid Assertions and Predicates: Use other methods instead of assertion and predicate as they disable TypeScript's type-checking features, leading to potential errors.
  • Interface Usage: Use interface only when necessary for enforcement or inheritance. Otherwise, use object.
  • Generics: Use generics only when there's a type relationship between data. Using them without context is meaningless.
  • Callback Return Type: Callbacks should return void when indicating no return value.
  • Callback Parameters: Only include necessary parameters in callbacks. Avoid optional parameters.
