JS Perf Notes closures & anon functions

jsfuncperf.js

// avoid using anon function cb's for high touch events
$("div").mousemove(function(){
	//this function is re-created every time w/ obvious overhead
});



//avoid re-creating Class methods in a constructor pattern. Use prototype instead
//instead of this... 
function Person(first, last){
	this.first_name = first;
	this.last_name = last;
	
	
	//methods 
	this.getFullName = function(){
		return this.first_name+ " " + this.last_name;
	}
	
}

//put getFullName in the prototype
Person.prototype.getFullName = function() {
	return this.first_name+ " " + this.last_name;
};


//	I would say the module pattern with private vars is fine when 
// initiating a class but for Factory'esque modules/classes reused a lot avoid closures
// If you need private vars for these high touch classes just use this._ convention
