What I did at work today

Things I should have already known but instead learned while writing a JavaScript book

• string.match(regexp) and regexp.exec(string) don’t do the same thing when it comes to global pattern matching.
• event.currentTarget is the element that is listening to the event, so you don’t have to rely on this.
• The beforeunload event.
• The difference between keyCode and charCode.
• How cookies work (!)

This list will grow.
