If you wanted your app component to be named mw app, how would you write your selectors for components?
1. @Component({
selector: [mw-app]:
template: `<h1>My App</h1>]
})
2. @Component({
selector: "mw-app";
template: `<h1>My App</h1>`
})
3. @Component({
selector: 'mw-app',
template: '<h1>My App</h1>'
})
4. @Component{
selector: mw-app:
template: `<h1>My App</h1>`
}
