A function which allows you to sort an array of objects by properties of the objects.

Sort By Property

function byProperty (prop, reverse, primer) {

	if (typeof reverse === 'undefined') { reverse = false; }
	if (typeof primer !== 'function') { primer = false; }

	var key = primer
		? function(x) {return primer(x[prop]);}
		: function(x) {return x[prop];};

	reverse = [1, -1][+!!reverse];

	return function (a, b) {
		a = key(a),
		b = key(b);
		return reverse * ((a > b) - (b > a));
	};

}

/* Example usage */

var arr = [
	{ a: "5", b: "e"},
	{ a: "10", b: "j"},
	{ a: "2", b: "b"},
	{ a: "6", b: "f"}
];

arr.sort(byProperty(a, true, funtion(x){return parseInt(x,10);}));

console.log(arr);
/*
Result:
[
	{ a: "2", b: "b" },
	{ a: "5", b: "e" },
	{ a: "6", b: "f" },
	{ a: "10", b: "j" }
]
