JavaScript arrays braces vs brackets

What is the difference between each of the following array definitions.

var myArray = [];

var myArray = {};

var myArray = new Array();

The first and third are equivalent and create a new array. The second creates a new empty object, not an array.

var myArray = []; //create a new array

var myArray = {}; //creates **a new empty object**

var myArray = new Array(); //create a new array
