Well Noted,
At the end of the tutorial I realized I had already used a bit of the event but if I had chosen to explain it detailed it would have been twice as long and would probably be too much to take on at once. Also the styling techniques are mostly in the .html so it wouldn't be too easy to bring out each component and explain but I'll do well to add way more comments in my code in the next tutorial. And lastly the ion-option is an input menu, so you have to explicitly list all the possible values as you would want them to be directly in the .html. There's no way to loop that.
