Pros
Easy to Learn:
Along with Python, Ruby is regarded as one of the easier languages to learn
Growing Community:
Ruby has a vast collection of open source code available within the Rails community.
Readable Code:
Ruby is mostly self-documenting which increases productivity because there is less need to write out separate documentation. As a result it makes it easier on developers to pick up existing projects.
Good for Rapid Application Development (RAD):
Rails framework makes it easy to accommodate changes.
|
Cons
Performance and Scalability:
There have been concerns that Rails applications are not as fast as Java or C, which is true, but for the majority of applications it is fast enough.
Not All Website Hosts Can Support Rails:
Alternatively, Rails application can be hosted on a Virtual Private Server (VPS) with Amazon EC2, Rackspace, or Linode.
Documentation:
It can be a bit challenging to find documentation for popular gems and libraries that heavily involve using mixins.
