How might I find the largest number contained in a JavaScript array?

I am having trouble getting this code to work. I have been at it for a while trying to figure it out. When I look at the console it just displays 0. What did I do wrong?

Here is my code:

var array = [3 , 6, 2, 56, 32, 5, 89, 32];

var largest= 0;



for (i=0; i<=largest;i++){

    if (array>largest) {

        var largest=array[i];

    }

}



console.log(largest);

The code below is fixed and should work. The problem was that in this line if (array>largest) { You were not providing the index of the array. By changing the code to this if (array[i]>largest) { it works. Notice that I added the [i] to the end of array in the if statement.

var array = [3 , 6, 2, 56, 32, 5, 89, 32];

var largest= 0;



for (i=0; i<array.length; i++){

    if (array[i]>largest) {

        largest=array[i];

    }

}









console.log(largest);
