No, just please no. Any moderately competent programmer can be productive in either Java or Javascript (+ Node.js). Javascript may help incompetent programmers feel productive because Javascript has fewer compile-time constraints but in the long run the cost of maintaining code written by an incompetent more than counteracts any perceived benefit that Javascript offers.
Well obviously the work of an incompetent programmer is going to increase the long run cost of maintaining code. That has nothing to do with the fact that Javascript is faster to develop in.
