How to override methods in localStorage?

myLocalStorage.js

((win) => {
  const nativeLocalStorage = win.localStorage;
  win.nativeLocalStorage = nativeLocalStorage; // keep the original usage

  class MyLocalStorage {
    setItem(key, value) {
      console.log('MyLocalStorage.setItem', key, value);
      nativeLocalStorage.setItem(key, value);
    }

    getItem(key) {
      console.log('MyLocalStorage.getItem', key);
      return nativeLocalStorage.getItem(key);
    }
  }

  const myLocalStorage = new MyLocalStorage();
  // Assign the newly created instance to localStorage
  Object.defineProperty(win, 'localStorage', {
    value: myLocalStorage,
    writable: true,
  });
})(window);
