Question

What is the proper way to declare a namespace? I’ve just read “Developing Large Web Applications” and the author suggests using:

if (!window.YourNamespace) {
  YourNamespace = {};
}

seems easy enough.. but I see all the javascript libraries for declaring namespaces and alternate methods. Isn’t there a standard way to do this? Any problems with the above?

Answer 1

  var Utils = {
        namespace : function(name) {
                return window[name] = window[name] || {};
        }
  };

or if you prefer your way use:

if (typeof window.YourNamespace === 'undefined') {
    YourNamespace = {};
}
