Douglas Crockford: Theory of the DOM

Here’s a set of 3 videos by Douglas Crockford on the DOM that were in between his JavaScript and Advanced JavaScript presentations. Pretty basic material, but you may find a few helpful hints. A few comments:

1. Comment hack for JavaScript hasn’t been necessary for 10 years!
2. language=javascript has been deprecated
3. type=’text/javascript’ is ignored if you use the src attribute
4. remove any event handlers of a node before deleting it due to MS garbage collection incompetencies
5. avoid trickling, bubbling is where the action is
