JS Arrays

Working with Arrays

//largest value in array
Array.max = function( array ){
    return Math.max.apply( Math, array );
};

//add multiple array values
function addArrayValues(arrayNameHere){
    var i
        , max
        , statTotal = [];

    sum=0; max=arrayNameHere.length; i=max; while(i--) sum += roll[i];
    statTotal.push(sum);
    return statTotal
}
