I've been using Yeoman ember generator for the past 1 month and now, I'd like to give ember-cli a try.
I run the generator and launch the app, everything works fine.
ember new my-new-app
ember server
but I'd like to know how does
{{content-for 'head'}}
in app/index.html works?
When looking at other examples from http://www.ember-cli.com/#tutorials, none of them are using this particular helper? Is it because they are using older version of ember-cli? Why weren't they using this content-for helper?
I'm pretty sure that ember.js doesn't have this content-for helper in default, so I'm guessing ember-cli wrote it somewhere? Where is it and what is it for?
Also, when I inspect the element of my-new-app page, the div tag of 'Welcome to Ember.js' appeared at the body tag instead of head tag? How is that possible? {{mind-blown}}
( in app/index.html, {{content-for 'head'}} is placed inside head tag)
