Why using EmberJS without EmberCLI is a Terrible Idea.
EmberJS is a front end javascript framework for writing single page web applications. It follows an MVC programming pattern. It is very similar to AngularJS and other similar frameworks.
One thing I believe sets EmberJS apart from the alternatives is the Ember-CLI project. Ember CLI is exactly what is says on the tin; a Command Line Interface for Ember applications. It has a lot of fantastic features such as: app folder structure, naming conventions, dependency management, continuous compiling and unit testing.
