💡 Hint

Common Mistakes

Using 'composables' instead of 'mixins'.

Placing mixins inside 'methods' or 'components'.

Mixins are added to the 'mixins' option in Vue components.

  const { count, increment } = [1]();
  return { count, increment };
}

💡 Hint

Common Mistakes

Trying to call a mixin as a function inside setup.

Using incorrect function names.

Composable functions are called inside setup and return reactive state and methods.

4fill in blank

hard

Fill both blanks to define a mixin and use it in a component.

Vue

const counterMixin = {
  data() {
    return { count: 0 };
  },
  methods: {
    [1]() {
      this.count++;
    }
  }
};

export default {
  [2]: [counterMixin]
};

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Naming the method incorrectly.

Placing mixins under wrong component options.

The method to increase count is named 'increment', and mixins are added in the 'mixins' array.

5fill in blank

hard

Fill all three blanks to create a composable and use it in a component's setup.

Vue

import { [1] } from './useCounter';

export default {
  setup() {
    const { [2], [3] } = useCounter();
    return { [2], [3] };
  }
};

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Importing or using mixins instead of composables.

Using wrong variable names inside setup.

The composable is imported as 'useCounter', and inside setup we extract 'count' and 'increment' from it.
