CODE EXAMPLE FOR JAVASCRIPT

Number.prototype.between = function(a, b) { var min = Math.min.apply(Math, [a, b]), max = Math.max.apply(Math, [a, b]); return this > min && this < max; };

//get min/max value of arrays
function getArrayMax(array){
   return Math.max.apply(null, array);
}
function getArrayMin(array){
   return Math.min.apply(null, array);
}
var ages=[11, 54, 32, 92];
var maxAge=getArrayMax(ages); //92
var minAge=getArrayMin(ages); //11
