Why are there so many RoR courses?

Question

Ruby on Rails

Recently, more and more often I stumble upon various Rails courses. Both paid and free. What is the reason for their number? Rails are so in demand? Or is the learning process easy and you can cut the dough for students? Or are there no less courses for other frameworks, and Rails just catches my eye?

Answer 1

Lot? Look at the number of courses in JS, PHP, Python, for example.
Here is a lot. There are few courses on Ruby and RoR, Russian-speaking ones are generally minuscule.

Answer 2

If you are interested in any topic, you will inevitably notice it everywhere and everywhere. They became interested in rails - and immediately a bunch of rail courses formed around. They were always there, you just didn't see them.
