The Birth and Evolution of Ruby on Rails

The Birth and Evolution of Ruby on Rails
Ruby, the programming language behind Ruby on Rails, was created by Yukihiro
Matsumoto in the mid-1990s. It was designed to prioritize developer happiness and
productivity. Matsumoto wanted to create a language that was both elegant and
practical, and that's how Ruby was born. Rails, on the other hand, was created by
David Heinemeier Hansson in 2004 while developing the Basecamp project. Rails
was extracted from Basecamp and open-sourced, quickly gaining popularity due to
its productivity-enhancing features.

Ruby on Rails is guided by several core principles, commonly referred to as the
"Rails Philosophy." These Ruby Rails Web Development principles include DRY
(Don't Repeat Yourself), Convention over Configuration, and the pursuit of
beautiful code. We'll explore how these principles shape the development process.
