Internet Explorer 8 can't see upper variables

Question

I have a big problem in front of me. I have to build soft that works on every modern browser and... IE8. Internet explorer can't see variables declared before function.

Model.something = function() {
  var someVariable = "something";
  (...)
  function process(err, data) {                 
    console.log(someVariable);     //internet explorer can't see this variable
  };
};

In every browser even in documentation I have, that JS see variables declared before. In IE8, this rule doesn't exist, anyone have any simple ideas? Any help will be much appreciated.

function process, can't see variable declared before. Everything see it. node.js, Chrome, Firefox, IE10++, but not IE8. — Pikachu, Apr 26 '14 at 16:30
Define "see it" is it undefined? Does it throw an error? Does it make your computer explode? :) — Sumner Evans, Apr 26 '14 at 16:31
I am 100% confident that this would work in every js engine, I do not have a window machine here but something else is hapenning here — ganmor, Apr 26 '14 at 16:36
@ganmor see jonathan.cone's answer. `console` is undefined in IE8. — Sumner Evans, Apr 26 '14 at 16:37
Whatever your problem is, it is not in the sample of code you provided. There's nothing wrong with it. — Evert, Apr 26 '14 at 16:33

IE8 isn't complaining about someVariable. It's complaining about console, which is undefined in IE8. See this question for more details.

It is ***BAD PRACTICE*** to use `console.log`s in production code for this exact reason. – Sumner Evans Apr 26 '14 at 16:40
