The best brief intro to jQuery I’ve seen. – post by avdigrimm
There are a bajillion posts about jQuery, all of which introduce you gently, so I will be brief: jQuery is all about a single namespace and kickass querying.
May I write to you? Every week or so you'll get a SIGAVDI newsletter with a few handpicked links to interesting articles, talks, or resources; an update on what I've published lately; and some reflections at the intersection of software and life. Replies go directly to me, and I try to respond to every single one (eventually!)
