I like Javascript, I write a lot of it. The progress that has been made through the years is pretty remarkable. Sometimes its hard to believe.<p>That said, javascript handles every number as a 64 bit float. For a lot of applications, that just doesn't matter. But to me, it does... its caused a lot of heart aches in my life, and for that I want to keep a better language for my server.
With servers being a commodity these days, I can only think of rare use cases where this would be helpful vs just scaling horizontally behind a load balancer. Also, in most real world systems I have seen, the real bottle neck is in the I/O and rarely in the business logic or server application level.
Forget the frontend. Just make it work 'faster' than node.js and people will use it.<p>If you're going to be writing it, prepare your release by writing at least 5 applications with it too.
