• Less code – Rails reduces the need for configuration files and automatically, it can handle a host of lower-level details even without you having to instruct it. Fewer lines of code are needed to implement the application. Fewer code means faster development and lesser bugs, which makes your code easier to understand, keep, and improve.

• Generators – Rails uses runtime reflection and metaprogramming and thus eliminates a lot of the boilerplate code that you would have to create. The remaining boilerplate code can be eliminated by using the built-in generator scripts in creating it. This gives you more time to concentrate on the business logic.
