Why the recommend Project Structure of tutorial is different from download the source code of “MyIonic2Project”

for example
in the recommend Project Structure of tutorial,under source code was seeing up .
src=“build/js/app.bundle.js”

in the MyIonic2Project,is not setting up
under is the source of MyIonic2Project in the /www/ index.html
src="cordova.js"
src="build/polyfills.js"
src=“build/main.js”
