no-unbound

{{unbound}} is a legacy hold over from the days in which Ember's template engine was less performant. Its use today is vestigial, and it no longer offers performance benefits.

It is also a poor practice to use it for rendering only the initial value of a property that may later change.

This rule forbids the following:

{{unbound aVar}}

{{some-component foo=(unbound aVar)}}
