I thought it would be a great idea to share with you guys:

Code:

        /****** Number guesser ******/

This would be a really hot computer game if it was still 1983.

**chrishirst** · 02-13-2007, 07:02 PM

LMAO !!

**ADAM Web Design** · 02-13-2007, 10:44 PM

That was totally uncalled for. Just because the script mentions an IRC chat room called #asshat and just because it resembles the end-of-term assignment in any high school computer class doesn't mean it's not hot.

This is a good game. I like the commnets also. It has become a habit nowadays to just write some code with no comment. The person who wrote the code made sufficient comments.

**ADAM Web Design** · 02-14-2007, 02:04 AM

If you need that many comments to figure out what's going on in the code, you aren't that good a coder. You should be able to deconstruct it and the other coder should be able to define functions and subs (depending on the language) with meaningful names.

**ProgMania** · 02-14-2007, 05:45 AM

He made this for the new javascript coders. Thats why he made comments.

The best way to learn Javascript is by understanding what it does... Not people telling you

At least that's how I learned
