Know when to use v-if (and when to avoid it)

Sometimes without v-if, it is more efficient to use v-show:

When v-if is turned on and off, it completely creates and destroys elements. V-show differs by creating an element and leaving it there, hiding it by setting its style to display: none.

If the components you need to switch are more expensive to render, this will be more efficient. On the other hand, if you don't need to use that component immediately, you can use v-if so that it skips rendering it and loads the page faster.
