how to declare and initialize global arrays in javascript


In my html code, I need a global array which I use throughout my application. How to create and initialize global array variable in javascript..

You can do it several ways :
In the global scope :

var arr = [];

Binding the array to the global namespace:

window.arr = [];

or, for running the code in other environments, where the global object is not necessarily called window:

    global.arr = [];
