JavaScript Containers
It's completely wrong that performance doesn't matter for the server side,  in fact it's the complete opposite.<p>Javascript is a fine language for client-side software because the client is paying for it (and the client's computer, tablet or phone is running idle most of the time anyway)<p>Firms that run web services pay dearly to run their servers on the cloud, expect to run at a high utilization fraction,  and if they ran their infrastructure on a slow language like Ruby they would be paying cloud bills 10x what they'd get for infrastructure written in Go.<p>The people who make the decision are paying the bills and that means they make a very different decision.
