javascript - Show last few characters when data binding in angularjs -


i understand how data binding works in simple example, i'm curious on how limit output display last 4 characters of whatever number put in, instead of entire number:

<!doctype html> <html ng-app>   <head>     <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.2/angular.min.js"></script>   </head>   <body>     <div>       <label>name:</label>       <input type="text" ng-model="number" placeholder="enter long number here">       <hr>       <h1>hello {{number}}!</h1>     </div>   </body> </html>

how go doing this?

from angularjs limitto docs do:

<h1>hello {{number | limitto: -4}}!</h1>

or see plunkr more options.
