React vs Vue: Which is Better for Composables?

What are composables in Vue and how do they compare to React hooks?

Composables in Vue are functions that allow you to encapsulate and reuse stateful logic. They are similar to React hooks, which also enable you to manage state and side effects in functional components. Both approaches promote code reuse, but they have different syntaxes and paradigms.

Can you give me an example of a composable in Vue?

Sure! A simple composable in Vue could be a function that manages a counter:

import { ref } from 'vue';

export function useCounter() {
  const count = ref(0);
  const increment = () => count.value++;
  return { count, increment };
}

How would this compare to a React hook?

In React, a similar hook would look like this:

import { useState } from 'react';

function useCounter() {
  const [count, setCount] = useState(0);
  const increment = () => setCount(c => c + 1);
  return { count, increment };
}

Both achieve the same functionality but use different APIs.

Which one is more efficient for larger applications?

Efficiency can depend on various factors, including the specific use case and how well the code is structured. Vue's reactivity system can be more efficient in some scenarios, while React's hooks offer flexibility and a large ecosystem. It's best to evaluate based on your project's needs.
