Can Javascript Prototype Pattern Performance Be Improved -


i have read creation of objects via prototypes faster , uses less memory closures because closures need re-create functions. accessing function on object's prototype little slower because needs traverse prototype chain further find function.

i wondering if adding reference in constructor prototype function increase performance minimal memory , initial setup impact. can achieved this...

function customer2(name) {     this.name = name;     this.greet = this.constructor.prototype.greet; } customer2.prototype = {     constructor: customer2,     greet: function () {         return this.name + ' says hi!';     } };

here add variable this.greet references prototype function save on traversal time.

could effective method @ increasing performance , keeping memory consumption low? cause side effects such problems inheritance?

jsperf link: http://jsperf.com/prototype-pattern-local-reference

so far jsperf seems support idea (except firefox seems favor closures setup doesn't make sense, maybe i've done wrong). of course, small example few test samples, , doesn't show memory consumption, thought might help.

i have code gives message when key number pressed: txtvalueofclause.addeventfilter(keyevent.key_typed, new eventhandler<keyevent>() { @override public void handle(keyevent t) { char ar[] = t.getcharacter().tochararray(); char ch = ar[t.getcharacter().tochararray().length - 1]; if (!(ch >= '0' && ch <= '9')) { system.out.println("the char entered not number"); t.consume(); } } }); now if press on wrong button , press backspace remove it, error message. how can add backspace input if statement? i have found answer: txtvalueofclause.addeventfilter(keyevent.key_typed, new eventhandler<keyevent>() { @override public void handle(keyevent t) { char ar[] = t.getcharacter().tochararray(); char ch = ar[t.getcharacter().tochar
