Some Javascript Questions

Featured Replies

Well the title says it all. I just would like to ask the community some questions about javascript that have been on my mind. One of you uber web gurus should be able to help me out.

 

So...

 

To what extent do you use javascript professionally? I've been reading books and references that describe subjects that are quite unnecessary in my eyes. I mean, how many of you web designers use prototypes and OOP in general? JQuery itself has been able to fulfill most of my needs so I'm just curious if it's worth it to continue learning such deep javascript fundamentals. This Douglas Crockford guy is giving me a big headache :blink:

 

Maybe I'm just being lazy because I want to hurry up and start learning more about php...

Not since Poet Master Grunthos the Flatulents' lower intestines leapt through his neck strangling his brain during a recital has the written word moved me so much. I got as far as this gem of a line in one particular OOP article before common sense overode further curiosity..

 

"Sub-type polymorphism suffers many of the same problems as inheritance: its "taxonomy" is artificial."
