If you want to push each function with its parameters in the manner you're doing, you'll have to wrap the function like so:

function wrapper(arg){
    return function(){
        console.log(arg);
    };
}


var ar = [];

console.log("pushing functions");

ar.push(wrapper(1));
ar.push(wrapper(2));
ar.push(wrapper('three'));

console.log("done pushing functions");

while (ar.length){
    var fn = ar.shift();
    console.log("calling ", fn);
    fn();
}

Alternatively, you could make a generic wrapper that takes a function, and arguments as parameters, and returns an anonymous function.

To answer your question more directly, the simplest way to run through an array in the manner you desire is like this:

while (array.length){
    var item = array.shift();
    ...
}
