Coming from the wonderful world of Ruby on Rails, I like the down-to-earth no nonsense design which makes it exceedingly easy to get interactive websites up and running in no time. In addition to the now famous "convention over configuration", there are many appealing aspects. Just to name a few: online guide and API documentation, testing is built in from the start, command line interface ember-cli makes it a snap to create and update projects, there's a wide range of add-ons covering pretty much all you need. The best part is that it's just plain fun to use and there's an enthusiastic community out there to help. If the online guides aren't enough, then there's plenty of information available on the Internet as well as several books.

Best, i like idea, i like ember-cli it's complex system. I like fast prototype with ember. It's really cool!

I like the prescriptive nature making it very productive out of the box. Further I like how the framework is open to extension as needed.
