Node.js is the software that allows you to run Javascript to create powerful server-side applications by using Google's V8 Javascript Engine. As a Node developer myself, I have always felt frustrated by seeing that Joyent, the company behind Node.s, was extremely conservative in terms of upgrading node to use the latest V8 version; the project was also struggling to get developers to actually contribute to code. This is why Fedor Indutny did the unthinkable: forked node and created IO.js. Today, the two projects are uniting possibly offering developers the best of both worlds

Actually, I'm a nodeJs developer myself. That's rather the point of it, it is not slow and can act very much like a full desktop application inside a web browser.
There is overhead for a scripted language, but you should probably understand that a computer in 2001 was powerful enough to run this script. It is now 2015 and even cell phones now have the horsepower to run these scripts so your argument about slowness has never actually panned out in operation.

Node is not inside the web browser. You can compile CommonJS (which node uses) into normal ECMAScript that can run in a browser, but the web browser definitely isn't running node. Processing power (and interpreter efficiency) has improved, but there is still a huge gap between ECMAScript in a browser and compiled C. Projects like asm.js and WebAssembly are trying to bridge that gap, but they haven't yet. The fact that they exist shows that there is a need for faster code execution than modern ECMAScript allows. We might as well be honest and up-front about this weakness. There are other reasons to use ECMAScript, and node.
