Functions, Part One: Your First Custom Function


Comments are closed.

John has a relaxed, yet informative style of presentation that quickly gets to the topic at hand without dealing with extraneous filler. Even though John's examples were in PHP, he highlighted 4 good rules for building a function in any language. This was a good presentation for the beginner as well as a nice refresher for the more experienced developer. John not only talked about what to do, but also why to do it.

I agree 100% with Eric. John doesn't just talk from slides, his slides expertly and creativly demonstrate what he is talking about. This wasn't just a syntax talk either, but suggested styles and conventions to serve as the first of many important building blocks.
