IE7 javascript error in for each loops

One of the reasons I like Flash is the fact that one piece of code will work on every browser. But not so with javascript. Case in point:

If you have an array (langArray) in javascript and want to loop through it the common way is this:

for each(var item in langArray){
...
}

but this causes IE 7 to choke. Instead you have to use the more verbose:

for(var item=0;item var item = langArray[i];
...
}
