Factory Functions & Singleton Pattern

What architecture pattern could this factory help implement?

const createObjectStore = (initialValues = {}) => {
  let store = { ...initialValues };
  
  return {
    get(key) {
      return store[key];
    },
    set(key, value) {
      store[key] = value;
      return value;
    },
    remove(key) {
      const value = store[key];
      delete store[key];
      return value;
    },
    clear() {
      store = {};
    },
    getAll() {
      return { ...store };
    }
  };
};

Model-View-Controller (MVC)
Observer pattern
Event sourcing
State management store
This factory could help implement a state management store: 1) It provides a centralized place for storing application data, 2) It offers controlled access to the data through get and set methods, 3) It provides ways to query (getAll), modify (set), and reset (clear) the state, 4) It could be extended to notify subscribers of changes (like Redux or Vuex), 5) It encapsulates the state and prevents direct manipulation, 6) This pattern is common in front-end applications for managing application state.
