A variety of cobbled together and totally inapplicable examples - worthless. Why?

For anyone with a modicum of skill or has google at their disposal (Jquery anyone?) the “tips” add little.
For the noob starting out, their brevity may appeal to you, until you realize there is NO cross-browser compatibility nor testing, just about every decried bad programming practice with Javascript is used, the “Auto search/complete” examples, if used, will have you prone and f*cked by hackers in minutes

all in all, worthless.
