Node.js

  • Developed by Ryan Dahl - 2009
  • Now sponsored by Joyent

Node.js

  • JavaScript on your Server
  • Event Driven
    • Nginx (C)
    • Netty (Java)
    • EventMachine (Ruby)
    • Twisted (Pyhton)
  • Runs on the V8 by Google

V8

V8 compiles and executes JavaScript source code, handles memory allocation for objects, and garbage collects objects it no longer needs.

 

function Point(x, y) {
    this.x = x
    this.y = y
}
var point = new Point(0,0)

point.x
# ebx = the point object
cmp [ebx,<hidden class offset>],<cached hidden class>
jne <inline cache miss>
mov eax,[ebx, <cached x offset>]
