1) v-if is not html. In html if you see <h3 ...> you immediately think, "there's a level-3 header element here". The thought "there's a level-3 header element here if..." is something new you have to learn for Vue.

2) Shorter is not always easier. For example, using quotes to delimit logical expressions makes it easy to make errors. See the misplaced quote here?

  <h3 v-if="user.role == 'admin" && user.name == 'james'>hello super user {{name}}</h3>
