Hi!
I have a question: is there any benefit in performance when using
for(elem in array) some_func(elem);
instead of
for(i in 0...array.length) some_func(array[i]);
Hi!
I have a question: is there any benefit in performance when using
for(elem in array) some_func(elem);
instead of
for(i in 0...array.length) some_func(array[i]);
From what I can see, in JavaScript it is generating the same code, so there should be no difference in performance.
This Haxe code
function some_func(el) trace(el);
var array = [2,4,6,8,10];
trace("loop1");
for(elem in array) some_func(elem);
trace("loop2");
for(i in 0...array.length) some_func(array[i]);
Generates this JavaScript
// Generated by Haxe 3.4.4
(function () { "use strict";
var Test = function() { };
Test.main = function() {
var some_func = function(el) {
console.log(el);
};
var array = [2,4,6,8,10];
console.log("loop1");
var _g = 0;
while(_g < array.length) {
var elem = array[_g];
++_g;
some_func(elem);
}
console.log("loop2");
var _g1 = 0;
var _g2 = array.length;
while(_g1 < _g2) some_func(array[_g1++]);
};
Test.main();
})();
Thanks for clarifying!
