useCallback in React vs. Methods in Vue

React’s useCallback to memoize functions:

javascript

Copy code

import { useState, useCallback } from 'react';

function MyComponent() {

  const [count, setCount] = useState(0);

  const increment = useCallback(() => {

    setCount((prevCount) => prevCount + 1);

  }, []);

  return (

    <div>

      <p>Count: {count}</p>

      <button onClick={increment}>Increment</button>

    </div>

  );

}

Vue equivalent (methods are automatically cached in Vue):

javascript

Copy code

export default {

  data() {

    return { count: 0 };

  },

  methods: {

    increment() {

      this.count++;

    }

  }

}
