My solutions to Loops challenge

// 12/21/2015
//Use a while loop, a for loop, and a forEach loop to find the largest number in an array.
//Use the following array for each of these loops.
//[1,5,2,9,6,3]
----------------------------------------------------------------------------------------------------
//My while loop solution:

var max=0;
var i=0;

function largest(array){
 while(i<array.length){
     if(array[i]>max){
         max=array[i];
     }
     i++;
 }
    return max;
}

largest([1,5,2,9,6,3]);
-----------------------------------------------------------------------------------------------------

//My do while loop solution:

var max=0;
var i=0;
function largest(array){
    do{
       if(array[i]>max){
           max=array[i];
       } 
       i++;
    }
    while(i<array.length)
    
    return max;
}

largest([1,5,2,9,6,3]);

-------------------------------------------------------------------------------------

//My for loop solution

var max=0;

function largest(array){
 for(var i=0; i<array.length;i++){
     if(array[i]>max){
         max=array[i]
     }
 }
    return max;
}

largest([1,5,2,9,6,3]);

----------------------------------------------------------------------------------------

//My forEach solution

function largest(array){
    var max=0;
    array.forEach(function(element){
        if(element>max){
            max=element
        }
    })
    
    return max
}

largest([1,5,2,9,6,3]);
