With analytics you can get to know how your app is performing. You can get to know things like:

  1. Time spent by users on your app.
  2. The bounce rate
  3. No of new and returning sessions.
  4. Pages views per session

and so on. If you app is not performing well on any of these points then you can identity and solve them.

All programming lanaguges are fairly good these days.

You will have to use both PHP and JavaScript to create an ecommerce website. Because PHP is server side and JavaScript runs only on brower. So when you will have to interact with the database then you will need the help of PHP because JavaScript cannot do such things.
