Go home, JavaScript, you're drunk...

wtf.js

function meta(f) {
  console.log("en meta");
  f();
}
var lista=[meta,meta,meta];
var fun=function() {
  console.log("funcion");
}
for(var i=0;i<lista.length;i++) {
  var item=lista[i];
  //(function(){
    var tmp=fun;
    fun=function() {
      item(tmp);
    }
  //}());
}
fun();

Just by reading the code, you can guess that it should print meta 3 times, then funcion. Right? Wrong. It's a stack overflow, and I'm not even sure why; it seems the item variable is not really captured in the function created inside the loop, so it ends up pointing to itself.

To fix it, uncomment lines 11 and 16. Now you have a separate scope, where item is captured.

Very intuitive, isn't it?

OK so changing line 14 to meta(tmp) still results in stack overflow. So apparently the problem is with tmp; if you uncomment lines 11 and 16 and then swap lines 11 and 12 so that tmp is declared outside the anon function, stack overflow happens again.

Closure FTW ... http://plnkr.co/edit/IuTI4O2GMPEZtEY2zHbc?p=info

function meta (f) {
  console.log('en meta')
  f()
}
var lista = [meta, meta, meta]
var fun = function () {
  console.log('funcion')
}
lista.forEach(function (item) {
  var tmp = fun
  fun = function () {
    item(tmp)
  }
})
fun()
