AS3: Getting the index of the highest value in an array

Is there any way to actually get the index of the highest value stored in an array?

Like for example

var rate:Array = [10, 15, 12];

how will I know if the highest value in the array resides at index #1?

You need only one loop. Copy the values into an array of objects that know both the index and the value, then use the sortOn method and return the last item in the resulting array.

var arr:Array = [10,15,12];
var temp:Array = [];
arr.forEach( function( item:int, index:int, self:Array ) :void {
    temp[temp.length] = {index:index, value: item};
});
var result:Array = temp.sortOn( "value", Array.NUMERIC ); // returns 1

There are many sorting algorithms in Data Structure which can help you achieve that. Bubble Sort is the highest among all.

Apart from that you can use the Math function in JS to achieve the same.

var highest = Math.max.apply(Math, values);
// Where 'values' is the array stored on your application.
