AngularJS : IF Statement inside "ng-repeat"?

I'm using AngularJS v1.2.9.

Inside ng-repeat, how do i use check the value of object and do action based on condition?

In English, something like:

if `X` is not null, then show `X`. Is it possible?

Here's my ng-repeat skeleton:

<li ng-repeat="r in results">
    <div>{{ r.title }}</div>
    <div>{{ r.location }}</div>
    <!--
    if ( r.date!=="null" ) {
        <div>{{ r.date }}</div>
    } else {
        <div>Date not confirmed yet.</div>
    }
    -->
</li>

I need to show r.date if it is not null. If it is null, then i say something else.

Please kindly help. Thanks all.
