Filter out duplicates in an array of objects using Underscore

filter.out.duplicate.objects.example.js

// bananas is a complex object
bananas = _.uniq(bananas, function(banana) {
   return JSON.stringify(banana);
});

// Caveat: order of properties in an object could be jumbled depending on how objects are created
// In such a case, this trick will not work. To prevent this, consider creating objects using a class-like declaration:

var BananaModel = function(data) {
	var self = this;
	if(data === undefined){
		self.name = "";
		self.datePicked = "";
	} else {
		self.name = data.name;
		self.datePicked = data.datePicked;
	}
};

var new Banana = new BananaModel({
	name: "Chiquita",
	datePicked: "May 6th"
});
