Why I don’t love JavaScript’s Module Pattern. Jonathan Snook points out that the module pattern (where private functionality is hidden in a closure and only public methods are revealed to outside scopes) makes code a lot harder to debug. I use the module pattern for pretty much everything, not because I want to keep stuff private but more to avoid any chance of leaking out in to the global namespace. If I need to debug a value I temporarily assign it as a property on the global window object. # 30th April 2009, 7:59 pm

Safari 1.3 has a JavaScript Console
My single biggest complaint about Safari in the past has been its terrible support for JavaScript debugging. Safari 1.3 has just been released, and tucked away in the Debug menu is a brand new JavaScript console option. It’s not as good as the Firefox equivalent (it throws up far too many “Undefined value, line: 0” errors for my liking) but it’s a big step in the right direction.
