filter filter is used to filter the array to a subset of it based on provided criteria.

In below example, to display only required subjects, we've used subjectName as filter.

Enter subject: <input type = "text" ng-model = "subjectName">

Subject:

<ul>

<li ng-repeat = "subject in student.subjects | filter: subjectName">

{{ subject.name + ', marks:' + subject.marks }}

</li>

</ul>
