Object Creation Methods

What pattern manages object state transitions?

class StateMachine {
  #state;
  constructor(initialState) {
    this.#state = initialState;
  }
  
  transition(event) {
    this.#state = this.#state.handle(event);
  }
}

Observer Pattern
Command Pattern
State Pattern
This implements the State pattern: 1) Encapsulates state-specific behavior, 2) Allows objects to change behavior when state changes, 3) Each state is a separate object, 4) Transitions are managed explicitly, 5) Reduces conditional complexity, 6) Common pattern for managing complex state machines.
Strategy Pattern
