For the sticklers out there this is what the document says verbatim:
Now as of late I have adopted this coding practice as my own and I must say that it has made my code flow more and has made my code a lot cleaner. I find my self directing events that have similar needs to one method instead of how I used to do things by writing the code twice (once in each event handler) with only one line of code difference between the two algorithms.
My questions are, is this really a best practice? and if so, is this coding style commonplace in real world applications?
