if value is between two numbers

Question

I want to be able to test whether a value is within a number range. This is my jQuery code...

if ((year < 2099) && (year > 1990)){
    return \

You could make your own method:

// jquery
$(function() {
    var myNumber = 100;
    try {
        if (myNumber.isBetween(50, 150)) 
            alert(myNumber + " is between 50 and 100.");
        else 
            alert(myNumber + " is not between 50 and 100.");
    } catch (e) {
        alert(e.message());
    }

});

// js prototype
if (typeof(Number.prototype.isBetween) === "undefined") {
    Number.prototype.isBetween = function(min, max, notBoundaries) {
        var between = false;
        if (notBoundaries) {
            if ((this < max) && (this > min)) between = true;
            alert('notBoundaries');
        } else {
            if ((this <= max) && (this >= min)) between = true;
            alert('Boundaries');
        }
        alert('here');
        return between;
    }
}

hope this helps.
