Coding bootcamps are all the rage these days, promising high-demand skills and a high salary. But where’s the number to support the hype? According to a survey from Course Report, the number of bootcamp graduates will nearly triple, from 2,178 in 2013 to nearly 6,000 in 2014. And the majority of them will be fluent in Ruby, taught in 57% of the courses. Course Report was founded in December 2013 by two former LivingSocial employees, Adam Lovallo and Liz Eggleston.
