So much like the last one , this article is going to focus on a piece of the javascript language that I had trouble understanding, and may be a point of confusion for you. Today I’ll be looking at closures and lexical scoping. Last time, I mentioned that Javascript has more in common with functional languages, than classical languages.

My current work at CakeDC allows me to be on IRC a lot – like all day. And while I’m often quite silent during the day, I do scan through a few PHP related channels and I’ve noticed a trend of PHP developers who just don’t get Javascript. Either they don’t have the experience, or they do have experience and think its icky.

I like many webdevelopers build a lot of forms. Forms are the bread and butter of web applications, and while making forms is getting easier for developers, users often still have a hard time with them. In these circumstances it is necessary to give them a help above and beyond ‘password’.

Creating gracefully degrading Javascript and CSS is pretty simple these days. I’m sure this has been written about a million times over as well.

GeSHi or the Generic Syntax Highlighter is a simple yet powerful syntax highlighter for many languages. Implemented in many CMS. When I wanted syntax highlighting for my postings I decided to implement GeSHi. I wanted to share my implementation of GeSHi as a CakePHP helper.
