// This function has three parameters
function average(num1, num2, num3){
    var result = (num1 + num2 + num3) / 3;
    // The function returns a value
    return result;
}

// The returned value from the function can then be used
// eg. it can be stored in a variable...
var myAverage = average(10, 15, 12);

// ...or displayed or used in another operation 
console.log(myAverage);
