fibonacci.js

function fib(n){
	var fib = [];
	fib[0] = 1;
	fib[1] = 1;
	for(var i =2, i <= n; i++) {
		fib[i] = fib[i - 1] + fib[i-2];
	}
	return fib[i];
}

finally figured this one out (but my expressions look pretty crazy). the hint is: get the sequence started manually to avoid infinite loop, use your loop to .push items to your array, and then instead of using integers, use references to the numbers (by index of your new array ex: newArray[newArray.length - 1]) in your new array.

this one was really hard for me. if you want to see my solution let me know.
