How JavaScript prototype chain enables inheritance by linking objects, controlling method resolution order and property lookup.

Access parent class methods and properties with super keyword to enable powerful inheritance patterns and method overriding.

Control method and property visibility with private members that restrict access to class internals from outside code.

Hide implementation details with private fields and methods that protect internal state from external manipulation.

Declare truly private class fields with # syntax that cannot be accessed outside the class, ensuring real encapsulation.

Use static class methods to attach utility functions directly to classes for organized, namespace-friendly code structure.

Static methods cannot access instance properties or this context, enforcing stateless operations and preventing state-related bugs.

Implement static utility functions on classes to provide reusable helpers without requiring class instantiation or state.

Why default-values creates better code organization and when to choose this pattern for maintainable applications.

Why element-extraction creates better code organization and when to choose this pattern for maintainable applications.
