#Full Stack Rails vs Full Stack JavaScript
Aspiring developers often ask “should I learn Rails or JavaScript to become a web developer?” Most students are concerned with picking a language that is easy to learn and that will offer them strong job prospects. Thankfully both Rails and JavaScript are great learning languages and open the door to many job opportunities.

##Learning
There are many aspects to consider when deciding whether a language is good for learning. Foremost among these is whether the language is beginner friendly, how extensive and support the community and resources are, and whether or not best practices are emphasized. 

###Beginner Friendly
Rails uses the Ruby programming language, which focuses on simplicity and productivity. The creator of Ruby, [Yukihiro Matsumoto](http://en.wikipedia.org/wiki/Yukihiro_Matsumoto), designed it to have an elegant syntax that is natural to read and easy to write. As such, printing out a “Hello world” is as easy as:
```ruby
puts “Hello world”
