Shortcut for fetching elements by their "role" attribute. This is for convenience and also to encourage the use of the role attribute for grabbing elements from the view.
So inside a view you can now do:
this.list = this.getByRole('people-list');Using this convention makes it much less likely that designers and JS devs accidentally break each other's code.
Take for example:
<nav class="people" role="people-list"></nav>It's very clear what that element will be populated with but also, the designer is free to add/change whatever classes they want, or even switch it to <ul> without breaking things.
