What is "web server" in NodeJS and why it should be used for enterprise apps in 2016 instead of Java/Go/PHP/Python?

Where are configs, logs, how to enable/disable HTTPS, HTTP2, gzip, caching and everything else possible in nginx/apache out of the box?

Why NodeJS should be used for backend, when NodeJS is a “right tool”?

Any real 2016 benchmarks/links NodeJS vs Go or vs PHP7 or?

What NodeJS can other platforms can’t?

Please provide links, statistics, benchmarks, business reviews, recommendations as much as possible.
