Ruby on Rails took the world by storm when it was first realized and I personally believe it is the reason you have all of these startups everywhere and such an explosion of web applications. It’s creator David Heinemeier Hansson aka DHH shocked the world when he first presented Ruby on Rails back in 2005. Rails has come a long way since then and it still holds its ground as one of the greatest web frameworks out there, across all languages. Since you just learned Ruby and I know you have fallen in love with it, because how could you not? We are now going to learn Rails and start to build our own web apps!
Rails has been since 2005 and there are a tremendous amount of tutorials out there, which is fantastic! However, it can be really hard to know where to begin. So follow what I have laid out for you here, in order, and you will be just fine ;)
