Ext.forEach

The cleaner and nicer the program, the faster it's going to run. And if it doesn't, it'll be easy to make it fast.

Ideally, yes. Practically, not quite there yet! http://triin.net/2011/03/02/Optimizi...h:_Not_so_fast!

There must be a way to do this sort of conversion. CoffeeScript converts their loops into traditional JavaScript loops, see this.

I'm just getting into CoffeeScript, having implemented it in SilkJS.

It seems like a lot of work to wrap ExtJS with CoffeeScript, but it could be interesting in the end. If you're just using client-side, though, it adds another build step and I think it might be difficult to debug generated JavaScript in the browser...

I found an Ext.each that should be converted to a plain for loop.

Ext.define('Ext.util.AbstractMixedCollection', {
    ...
    removeAll : function(items){
        Ext.each(items || [], function(item) {
            this.remove(item);
        }, this);

        return this;
    },
    ...

Fixed in nightly:

    removeAll : function(items) {
        items = [].concat(items);
        var i, iLen = items.length;
        for (i = 0; i < iLen; i++) {
            this.remove(items[i]);
        }

        return this;
    }

There are quite a lot of function iteration fixes we have in. Not all of mine mad it in I don't think but quite a few.
