I agree... some of them are handy tricks that don't make the code obfuscated or less readable, but not all. Some people think code like this is clever or desirable, too. Also, I've actually seen code in jQuery plugins such as if(condition) //{ //save a byte! action(); //} // save a byte! as if leaving out the braces will actually make your code run faster, or make a real difference after minification. I could easily see that sort of person thinking this article is like an elite JavaScript style guide.
