That's true ramblerman, and actually I wrote some of this in the console window of Chrome. The real point I was trying to prove (mostly to myself) is that javascript can work as a server-side scripting platform to quickly create short scripts. Node is simply my interpreter for it (and more). That actually points out another bonus. I can POC something in javascript in a browser window, and if I want to graduate it to a server side script its mostly a copy-and-paste operation.
The post is mostly about convenience. I use javascript all the time. Now I can use it more. I love ruby, I just end up having to relearn it every time I use it because I don't use it often. Node is just the vehicle of that convenience.
Whoa, who said anything about full stack replacement. I use a variety of stacks, I was simply pointing out that since I'm using Javascript all over the place anyway, I might start using it on the server side as well. Things I use Ruby for generally amount to one-off jobs or shell-scripts. I constantly have to remind myself of the syntax, since all I use all day long are variants of C syntax(C#, java, javascript). It'll take me 10 minutes to whip up what would take me 30 in ruby, simply because I don't use ruby often enough to internalize the syntax. node provides me with a way to write the same shell scripts in javascript.
