Pro Huge number of generators for scaffolding your project
Yeoman generators allow you to quickly set up a new project. Invoked with the scaffolding tool 'yo' they provide a boilerplate & tooling selection. There are over 1000 generators, including generators for ember, angular & backbone, to choose from, the majority of which are community maintained.

Con Combining Yeoman and backend frameworks can bring problems
