Short Answer from someone who has been hiring front-end devs recently, no. I've interviewed people from 6-12 week bootcamps who don't know enough to build even the most basic of features. My feelings on the ROI of most bootcamps is another discussion topic entirely. @tomhodgins said it best. I think that even the smartest, fastest learning, hardest working individuals would still take around 6 months of daily learning and practice to be proficient enough to work full-time doing JavaScript.
