What is the proper way of importing bower packages unto a module?

i am trying to build an app using ember and ember-cli… and i am so confuse by the new convention of what ember-cli offers… i know for sure that it is base heavily on es6 module syntax… and im also a newbie at this… anyways. i saw this post on ember-cli documentation…

there seem to be 2 ways of managing dependencies… standard non-amd and standard-amd…

what is the preferred way? and also what is .jshintrc?

thanks
