JavaScript Roundup

Two JavaScript related posts for you this morning. The first post comes from John Resig entitled “JavaScript Performance Stack“. In this post, John goes over how JavaScript interacts with the different parts of a browser engine and will give you an idea of how these parts are connected and related to each other. The second post comes from dow.ngra.de and is a list of JavaScript puzzlers. These are along the same lines as the Java Puzzlers book Josh Bloch and Neal Gafter put out; interesting bits of code that look harmless, but do something unexpected when run.
