What problem does this feature solve?

I'm writing a Vue.js app using vue-router. I mistyped the 'component' field for route, like that:

const router = new VueRouter({
    mode: 'history',
    routes: [
        // some other routes
        { path: '/dashboard', compoment: DashboardComponent },
        // more components
    ]
});

The result is nothing is rendered on this route. And I've spent 2 hours debugging it because there's no error/warning if the component field is not set.
My suggestion is to throw an error (or at least put a warning to console.log() ), that way it'd be more clear that the user didn't provide a component for render and that's why nothing is rendered.

What does the proposed API look like?

No API changes, just add the error/warning if the component is not set.
