Say, you have an array of numbers with over 100 elements and you need to find the highest and lowest values. How do you do that?

**Way 1:**

You can do that by using these two simple functions:

function maxVal(givenArray):Number { var max = givenArray[0]; for (var ma:int = 0; ma<givenArray.length; ma++) { if (givenArray[ma] > max) { max = givenArray[ma]; } } return max; } function minVal(givenArray):Number { var min = givenArray[0]; for (var mi:int = 0; mi<givenArray.length; mi++) { if (givenArray[mi] < min) { min = givenArray[mi]; } } return min; }

As you can see, the code in both of these functions is very similar. The function sets a variable - max (or min) and then runs through the array with a loop, checking each next element. If the next element is higher than the current, set it to max (or min). In the end, return the number.

**Way 2:**

function maxVal(givenArray):Number { return Math.max.apply(this, givenArray); } function minVal(givenArray):Number { return Math.min.apply(this, givenArray); }

We use the built-in Math.max function and feed it the givenArray.

Example of using the functions:

var numbersArray:Array = [5, 21, 876, 5465, 234, 1, 0.1, 354, 3476]; trace(maxVal(numbersArray), minVal(numbersArray));

Output: 5465 and 0.1.

Thanks for reading!
