I'm starting on Ionic, I followed this tutorial , everything However, when I go to index.html and put the variable {{firstname}}, it shows in the browser as if it were going through html, unlike it after writing {{firstname}} and not the date of the array.
<ion-content ng-controller="StudyingController">
<button class="button" ng-click="getData()">Test</button>
<br>
name: {{firstname}} {{lastname}}
</ion-content>
