> Just use stuff that works, and that most people already know. Python, Perl, Ruby, jQuery, PHP, etc. Any of those have all the tools you need, proper documentation, millions of Stack Overflow discussions, and exceptional ecosystems and communities.

Most of the stuff you mentioned is also highly inefficient and requires much more computational resources to reach the same level of service.

Java is also conspicuously missing from that list, even though it has a solid infrastructure and ecosystem.
