Clarification regarding ionic project creation

Ionic Framework ionic-v3
1

I created application using ionic start myApp, when i referred ionic start documents there is multiple option is available to create ionic app.
(i.e) $ ionic start myApp blank
_ $ ionic start myApp tabs --cordova_
I need difference between ionic start myApp blank vs ionic start myApp tabs --cordova
If any folder structure is changed or cordova library is updated.

Why don’t you just run it twice and compare the results?

3

I checked that scenario, but no changes is identified while create application.

Then irt probably doesn’t do anything.

I created an issue about that: https://github.com/ionic-team/ionic-cli/issues/2543
