// if you want the whole series of fibonacci

var fib = [0, 1];
var n = 10;    // you can change this value
if (n == 1 || n == 2) {
    console.log(fib);
}
else {
    for (var i = 2; i < n; i++) {
        fib.push(fib[i-1]+fib[i-2]);
    }
    console.log(fib);
}


// if you want only the nth value

var fib = [0, 1];
var n = 10;    // you can change this value
if (n == 1) {
    console.log(fib[0]);
}
else if(n == 2){
    console.log(fib[1])
}
else {
    for (var i = 2; i < n; i++) {
        fib.push(fib[i-1]+fib[i-2]);
    }
