'var gpio' INVALID SYNTAX in IDLE3, Raspberry Pi

Question

I'm new to Python and Raspberry Pi. I'm trying to drive a stepper motor with the Rpi from this website: http://www.sundh.com/blog/2014/02/control-stepper-motors-with-raspberry-pi-and-node-js/

I find an error for my gpio variable in python. It says "Syntax Error: Invalid Syntax". Would really appreciate any help.

The error is on the first line. 'gpio' was highlighted in RED. IDLE 3 says syntax error.

Below is my code:

var gpio=require("pi-gpio");
stopMotors = false;
function sleep(milliseconds) {
 var start = new Date().getTime();
 for (var i = 0; i < 1e7; i++) {
 if ((new Date().getTime() - start) > milliseconds){
 break;
 }
 }
}
gpio.open(16,"output",function(err){ 
 console.log("Pin 16 open"); // Opens pin 16 as output 
});
gpio.open(18,"output",function(err){ 
 console.log("Pin 18 open"); // Opens pin 18 as output 
});
// Runs motor in the set direction
function move() {
 gpio.write(16, 1, function() { 
 sleep(1000); 
 gpio.write(16, 0, function() { 
 sleep(1000); 
 if(!stopMotors)move(); 
 }); 
 }); 
}
function stopMotor() {
 stopMotors = true;
}
// Changing direction of motor
function left() {
 stopMotors = false;
 gpio.write(18, 1, function() { 
 move();
 }); 
}
// Changing direction of motor
function right() {
 stopMotors = false;
 gpio.write(18, 0, function() { 
 move();
 }); 
}

BTW is this even python? Im entering these in IDLE3.

Can you help me please?

I would assume it's JavaScript as node.js is " an open source, cross-platform runtime environment for server-side and networking applications. Node.js applications are written in JavaScript, and can be run within the Node.js runtime on OS X, Microsoft Windows, Linux and FreeBSD."
