Javascript array declaration

Question

What object will this create? I've never seen this declaration before so I'm just wondering.

`myArray([]);
 for(someValue = 0; someValue < someOtherValue; i++)
 myArray.push(something[i]);
`

Thanks for any insight you can give me.

EDIT : I Update the code some more to gime some more info. myArray doesn't seem like a function to me in the code. This is used in an AjaxCall. Some lines after it is used like this

So unless I missed something I don't think it is a function.

• Waleed Khan: Probably an object of type myArray.
• Bergi: [] is an array literal. What is that myArray function?
• Igor Dymov: it's a function call with an empty array as an argument
• Ben Lefebvre: Exactly what I'm wondering. Looks like an array to me.

Answer 1

[] is an empty array literal and it's being passed to a function myArray which accepts an array as an argument. This is not a declaration, it's just a function call. It could be defined like this:

function myArray(array) {
 for (var i = 0; i < 5; i++) {
 array[i] = i;
 }
}
var array = []; // empty array to be filled later
myArray(array);

This fills the array with the numbers from 0 to 4.

Answer 2

You're calling the function myArray and passing in any empty array literal, which is defined by these: []. What's the myArray function look like?

Answer 3

If myArray is a function you are calling then [] will pass an empty array as the first argument to it

Its same as doing

var arr = new Array();
myArray(arr);
