Make watchers clearable via $watch

[Gumball12]

const useStore = defineStore('store', {
  state: () => ({
    countA: 1,
    countB: 1,
  }),
  watch: {
    countA: () => {
      console.log('changed');
    },
  },
});

const store = useStore();
store.countA = 2; // "changed"

store.$watch.countA(); // clear watch.countA
store.countA = 3; // nothing

Topic

Can watchers be cleared via the $watch method?

Before

• No, watchers cannot be cleared via the $watch method.
• The current implementation in src/index.ts does not provide a mechanism to clear watchers.
• The $watch property in the store is a readonly reference to the watch handlers defined in the store options.
• There is no functionality in the code to remove or clear a watcher once it has been set.
• The tests in __tests__/index.test.ts do not include any scenarios for clearing watchers via the $watch method.

After

• Yes, watchers can now be cleared via the $watch method.
• Added a method to clear watchers in src/index.ts.
  • Implemented a function to remove watchers from the store.
  • Updated the $watch property to include a method for clearing watchers.
• Updated tests in __tests__/index.test.ts to include scenarios for clearing watchers via the $watch method.
  • Added tests to verify that watchers can be cleared and do not trigger after being cleared.
• Updated documentation in README.md to include instructions on how to clear watchers via the $watch method.
