Node.js

• Developed by Ryan Dahl - 2009

Node.js

• JavaScript on your Server
• Event Driven
  • Nginx (C)
  • Netty (Java)
  • EventMachine (Ruby)
  • Twisted (Pyhton)

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>]
