Creating the route mixin

In this part, we will create the component mixin to be re-used in other components. Follow these instructions to create the component correctly:

1. Create a new file called changeComponent.js in the src/mixin folder and open it.
2. This mixin will have a method called changeComponent, which will emit a 'change-component' event with the name of the new component that needs to be rendered, and the userId:

export default {
  methods: {
    changeComponent(component, userId = 0) {
      this.$emit('change-component', { component, userId });
    },
  }
}
