Declaring array of objects

Use array.push() to add an item to the end of the array.

var sample = new Array();
sample.push(new Object());

To do this n times use a for loop.

var n = 100;
var sample = new Array();
for (var i = 0; i < n; i++)
    sample.push(new Object());

Note that you can also substitute new Array() with [] and new Object() with {} so it becomes:

var n = 100;
var sample = [];
for (var i = 0; i < n; i++)
    sample.push({});
