I have an app in Ionic 2 and its very simple just two pages (Game and Results). To show the questions to be answered there is an array 'myQuestions' that is instantiated with data from another constant array of questions. Every time a question is answered I delete a question from 'myQuestions' and finally the second page shows the results. In the results page there is a 'play again' button and here comes the problem because when I go to the Game page, the array is incomplete. It is not reinstantiated, the componenent its not created again but instead it is reused, until I got 0 questions available and the site crashes. How can I solve this?
If you use setRoot to navigate back to the Game page, you can put the code that generates myQuestions array in ionViewDidLoad(). The page constructor loads once when the application runs because it is single page app. The application does not refresh when you change the view, they use Ajax request to load other view instead. IonViewDidLoad() fits in the purpose of listening the loading view and runs any time you visit the page.
