"But $.each is slow!" ..use fn arrEach and objEach then!!

fn arrEach and objEach

// arrEach and objEach plugins
// code under MIT license by Marc Grabanski http://marcgrabanski.com
// jsperf tests: http://jsperf.com/each-vs-fn-arreach-and-objeach/2

$.arrEach = function(arr, cb){
    for (var i = 0, item; item = arr[i]; ++i) {
       cb.apply(item, [i, item]);
    }
    return arr;
}

$.fn.arrEach = function(cb){
   return $.arrEach(this, cb);
}



// examples using array each
$.arrEach(["foo", "bar"], function(i, item){
    console.log(i, item);
});

$(["foo", "bar"]).arrEach(function(i, item){
    console.log(i, item);
});





// JSPerf results show mixed results of faster/slower for objEach, but huge gains for $.arrEach. 
// This is why you test everything folks!!

$.objEach = function(obj, cb){
    for (var i in obj) {
       cb.apply(obj[i], [i, obj[i]]);
    }
    return obj;
}

$.fn.objEach = function(cb){
    return $.objEach(this, cb);
}


// examples using object each
$.objEach({"foo":"bar", "baz":"bla"}, function(i, item){
    console.log(i, item);
});

$({"foo":"bar", "baz":"bla"}).objEach(function(i, item){
    console.log(i, item);
});

psst. You're leaking an i variable ;)

psst. You're leaking helpful pointers. Fixed.

:D anytime dude
