Here is a not-exhaustive list of what I would consider as "magic" in the code: 1) As mentioned before, behaviors that happen because of the name of your classes, properties, files This kind of magic would happen thanks to a parser that would extract your classes / properties / files names and then look for specific patterns. Upon finding such patte...

It reduces duplication and "no brainer" code to write. When I tell you that "the only thing you need to do is to add your file in folder Z and you're done", ...
The reason I am strongly suggesting to avoid magic as much as possible is how hard it is to deal with it when things go wrong. In order to illustrate my statement, please allow me to share a story, starring Bob, a random developer. Story starts, Bob is hired to work on a codebase where there is one magic behavior implemented. This codebase is a web...
Aug 19, 2010 · Magic numbers are any number in your code that isn't immediately obvious to someone with very little knowledge. For example, the following piece of code: sz = sz + 729; has a magic number in it and would be far better written as: sz = sz + CAPACITY_INCREMENT;
