function a(foo, bar[x]){
//perform operations here
}
Appreciate it in advance.

Due to the dynamic nature of JavaScript, you cannot always depend on a variable being an array. To work around this limitation, you can implement a check like the following (not perfect, but gets the job done):
function processItems(item, items) {
if (!Array.isArray(items))
items = [items];
// Now that you have confirmed items is an array, you can proceed
}
In my experience, naming arrays in the plural form, such as "items" instead of "item", tends to be more helpful. Your mileage may vary.
Absolutely, it is completely feasible. As you might have observed, there is no need to explicitly specify the type of variables in JavaScript. For instance, when you declare a variable using var a = 1, JavaScript automatically infers the type. Similarly, when passing an array as an argument to a function, you don't have to inform JavaScript that it's an array.
function myFunction(foo, array){
}
Here's how you can call this function:
var myFoo = { name: 'Hello' };
var myArray = [ 1, 2 ];
myFunction(myFoo, myArray);
I trust this explanation proves helpful.
