What is Rails?

Rails is a full-stack Ruby web framework built on convention over configuration.

📖 Key ideas

  1. Rails follows MVC: Models, Views and Controllers.
  2. "Convention over configuration" means sensible defaults replace setup files.
  3. "Don't Repeat Yourself" (DRY) keeps each idea in one place.
  4. rails new shop creates a ready-to-run app.
  5. GitHub, Shopify and Basecamp were built with Rails.
💡 Real-life example: Like a furnished flat: the furniture is already where most people want it, so you move in and start living.
