As with much of PHP, values are copied in to the closure by default but you can use an ampersand to specify JavaScript-style pass-by-reference instead. # 19th July 2008, 10:58 pm

quipt (via) Extremely clever idea: Cache JavaScript in (which persists between page views and can hold several MB of data), but use document.referrer to check that an external domain hasn’t loaded the cache with malicious code for an XSS attack.

Opera recommend “bug detection”, a step up from object detection and browser sniffing where your JavaScript includes mini unit test style fragments of code designed to test if buggy behaviour you are working around still affects the user’s browser. # 4th July 2008, 8:24 am

eval() Kerfuffle. The ability to read supposedly private variables in Firefox using a second argument to eval() will be removed in Firefox 3.1. # 2nd July 2008, 9:24 pm
