My javascript script for the Fibonacci Sequence

Fibonacci.js

// Fibonacci Sequence - Enter a number and have the program generate the Fibonacci sequence to that number or to the Nth number.

var i;
var fib = [];

fib[0] = 1;
fib[1] = 1;

document.write(fib[0] + ", " + fib[1] + ", ");

var fibonacci = function(n) {

	for(i=2; i<=n; i++)
	{
	    fib[i] = fib[i-2] + fib[i-1];
	    document.write(fib[i] + ", ");
	}

}

fibonacci(100);
