Guys Pls Help me out of this. I'm new here..

How to check whether the input is fibonacci or not? This is node.js    

var n=5,s,a,fib;

function isPerfectSquare(s){
var a=Math.sqrt(s);
return (a*a == s);
}

function isFibonacci(n){
s=(5*Math.pow(n,2)+4 || 5*Math.pow(n,2)-4)
return s;
}

//How to fix this line. I don't know how to check perfect square conditions 
if(isPerfectSquare(isFibonacci(n)) || isPerfectSquare(isFibonacci(n))) // 
checks the given input is fibonacci series

{
fib=Math.round(n* 1.618); // finds the next fibonacci series of given input
console.log("The next Fibonacci number is " + fib);
}

else
{
console.log("The given number is not a fibonacci number");
}
