Storing a variable in the JavaScript 'window' object is a proper way to use that object?

Question

(Maybe) I just solved a my problem (How to update front-end content after that a form is successfully submitted from a dialog window?) by \"storing\" / \"saving\" a variable

Answer 1

Another pattern to make a unique namespace in your application.

function myApp()
{
    var value = 5;
    function addToValue(x)
    {
         value += x;
    }
}()

If you want functions/values to be accessible afterwards you can store them in an object like this:

function myApp()
{
    this.value = 5;
    this.addToValue = function(x)
    {
         this.value += x;
    }
}
var myInstance = new myApp();
