Why Choose Ruby for a beginner. Why not JS and NODE EXPRESS or PHP that would have made this more simple for people who are new to programming and looking to get a job.
There are plenty of Ruby jobs out there, and it's an elegant and well-designed language that's got a mature framework. Especially crucial for relative beginners: it doesn't have the flavor-of-the-week problem that JS does, nor is its most prominent example a legacy mess, as Wordpress is for PHP.
