Dealing with JavaScript Scope

Over at Ajaxian, they've offered up a useful tip for dealing with code that exists in the global namespace and is conflicting with other scripts: move it into its own function. Example:

(function() {

// do you stuff here!

})();

What's the global namespace? That's the window object. Any time you instantiate a global variable, it is automatically part of the window object.

var myvar = 5;
alert(window.myvar); // alerts '5'

For more information on scope, be sure to check out my recent article on Digital Web on that very topic.
