Question

Why are the square brackets used in the following string?

@Directive({

          selector: '[mwFavorite]'

})

1. so the selector can find a match on an element attribute

2. to call on multiple instances of the same component type

3. so Angular can find a match and apply the directive

4. to repeat markup when looping over some data
