How can I improve component reusability in Vue.js?

To improve component reusability in Vue.js, you can use props to pass data, emit events for communication, and create mixins.

What are mixins and how do they help with reusability?

Mixins are a flexible way to distribute reusable functionalities for Vue components. They allow you to define a set of options that can be shared across multiple components.

Can you give an example of a mixin?

Sure! Here's a simple mixin example:

const myMixin = {
  data() {
    return {
      sharedData: 'This is shared!'
    };
  },
  methods: {
    sharedMethod() {
      console.log('This method is shared!');
    }
  }
};

You can then include this mixin in any component to access sharedData and sharedMethod.

Are there any downsides to using mixins?

Yes, mixins can lead to naming conflicts if multiple mixins define the same data or methods. They can also make the code harder to trace, as it may not be clear where certain properties or methods are coming from.
