I am trying to create a while loop in Javascript. I have a an array called numbers that contains 5 numbers. I also have a variable called bigone that is set to 0. I am trying to write a while loop that has an if statement that compares each value in the array to bigone. When the number in the array slot is greater then bigone, I want to assign that number to bigone. I cant figure it out. Here is what I have so far but it wont work. Yes this is homework and NO I am not asking for the answer, just for some guidance in the right direction. Here is as far as I have gotten :

while ( numbers.length < 5 ) {

    if ( numbers > bigone ) {

    bigone = numbers

    }

  }

Any ideas?

Implement a counter so you can access the values in the array.

var i = 0;

while(numbers.length < 5 && i < numbers.length)

{

    if(numbers[i] > bigone)

        bigone = numbers[i];



    i++;

}

This is the same loop but with for. Not sure why you are checking if there are 5 or less elements in the array but ok. This checks the length on every iteration.

for(var i = 0; numbers.length < 5 && i < numbers.length; i++)

{

    if(numbers[i] > bigone)

        bigone = numbers[i];

}

A better method to just check it once is to wrap the for loop in an if statement like this:

 if(numbers.length < 5)

 {

     for(var i = 0; i < numbers.length; i++)

     {

         if(numbers[i] > bigone)

             bigone = numbers[i];

     }

 }
