When do you reuse modules?

Sometime you may need to create multiple instances of a module.

For example, it is needed in the below cases,

1. If multiple stores that use the same module
2. Register the same module multiple times in the same store.

In those cases, you need to assign to a variable and export it for reusability,

const MyReusableModule = {
// state
// mutations, actions, getters...
}
