Ruby on Rails (RoR), launched in 2005, revolutionized web development by introducing a convention-over-configuration paradigm that simplifies the process for developers and promotes faster delivery of applications. Despite misconceptions regarding its performance and scalability, RoR remains a viable choice for various applications, especially for MVPs and high-traffic platforms like Airbnb and GitHub. Recent updates have addressed performance issues, and the language and framework continue to evolve, maintaining Ruby's relevance among the top programming languages.
