Change made -> from "build/js/app.bundle.js" to "build/main.js"

i was reading through tutorial “project structure”.

  1. i could not find “build/js/app.bundle.js”, as it’s comments said it " concatenated file containing Ionic, Angular and your app’s JavaScript." i tried to search for this functionality in other file names.
  2. i found “build/main.js” to be most probable.
    but i don’t know, my spec
