    JavaScript:

    function isFibo(n) {
    // Write your code here
    let fibonacciSequence = [0,1];
    
    let lastFibonacci = 1;
    while(lastFibonacci <= n){
        if(lastFibonacci === n) return "IsFibo";
        
        fibonacciSequence.push(lastFibonacci);
        lastFibonacci = fibonacciSequence.at(-2) + fibonacciSequence.at(-1);
    }
    
    return "IsNotFibo";
}
