stuff is an object and push is a method of an array  So you cannot use stuff push       Lets say you define stuff as an array stuff       then you can call push method on it   This works because the object key value  is well formed   stuff push    name    this  attr  checked         Whereas this will not work because the object is not well formed   stuff push     this  attr  value     this  attr  checked        This works because we are treating stuff as an associative array and added values to it  stuff   this  attr  value        this  attr  checked

push   is a method of the Built-in Array Object  It is not related to jQuery in any way   You are defining a literal Object with     Object var stuff         You can define a literal Array like this     Array var stuff         then   stuff push element       Arrays actually get their bracket syntax stuff index  inherited from their parent  the Object   This is why you are able to use it the way you are in your first example   This is often used for effortless reflection for dynamically accessing properties  stuff          Object  stuff  prop      value      assign property of an                              Object via bracket syntax  stuff prop     stuff  prop       true
