pass function multiple integers and iterate over them

The counts I get are fetched from an api, for simplicity i've just hard coded integers to represent my problem.

I need to iterate through vars fbCount, tweetCount, and pinCount, and do something when they're over 1k.

I'm a ruby guy, pretty sure i'm making a silly move. The error I get is: uncaught type error object 18000 has no method 'each'

var fbCount        = 18000,
    tweetCount     = 0,
    pinCount       = 0;

function somethingByCount(count) {
    count.each(function() { 
         alert("firing each count")
    });
  }

somethingByCount(fbCount,tweetCount,pinCOunt);

well you can use an array

    var fbCount        = 18000,
    tweetCount     = 0,
    pinCount       = 0;

    var data=new Array(fbCount,tweetCount,pinCount);

function somethingByCount(count) {
    $(count).each(function() { 
         alert("firing each count")
    });
  }

somethingByCount(data);

use arguments to get the list of arguments

Using $.each() to iterate - cross browser

function somethingByCount() {
    $.each(arguments, function(idx, val) { 
        alert("firing each count:" + val)
    });
}

Demo: Fiddle

Using native Array.forEach() to iterate - only on modern browsers

function somethingByCount() {
    Array.prototype.forEach.call(arguments, function(val, idx){
        console.log("firing each count:", val)
    })
}

Demo: Fiddle

The function expects the argument to be an array, so you have to wrap them in brackets:

somethingByCount([fbCount, tweetCount, pingCount]);

Or you could change the function to use the arguments variable, which contains an array of all the parameters:

function somethingByCount() {
    arguments.each(function() {
        alert("firing each count");
    });
}
