new MyObject(); vs new MyObject;

In some articles I seen following statement to create new object in JavaScript:

var myObject = new Object;

and at some sites:

var myObject = new Object();

In there is any difference between two statements or one is just shorthand?

Answer 1

There’s no difference. Parentheses are optional when using a function as a constructor (i.e. with the new operator) and no parameters. When not using the new operator, parentheses are always required when calling a function.

As noted in another answer, it’s generally preferable to use an object literal instead. It has the following advantages over using the Object constructor:

• Allows concise initialization of properties (e.g. var foo = { bar: "cheese" };)
• Shorter
• Possibly faster
• Unaffected in the (unlikely) event of the Object function being overwritten.
