Hi there I was doing some research on Ruby and couldn't fully understand what it's suppose to do, but I want to use it to build an application and sell a product. Would Ruby do this for me? I heard some much of it but not sure how to use it.
Ruby is a programming language and RoR is an application framework for the Ruby. At a high-level, an application framework is a collection of classes that provide common application functions such as data access, logging, caching, cryptography, validation, security, etc. If you are more familiar with PHP then take a look at CakePHP, which models RoR concepts.
