JavaScript Explanation
This code creates a function called calculate.
After entering your age and name, it stores them in two variables called myname and myage respectively. It then goes on to calculate your birth year based on today's date, and stores it in a variable called birthyear.
Finally it stores the message contents in a variable called text, calls the navigator.notification.alert function and displays the result as a popup.
The navigator.notification.alert function is a Core Cordova Plugins function that displays a popup dialog box on the screen. The third argument displays the text Welcome to Monaca! as the title of the dialog box.
