The moths of programming are ideas in the software engineering industry that have become pervasive due to virality rather than reality. Although they may have some truth to them, they are often inaccurate, misleading, distracting or even damaging. I call them moths because they flutter around in a programmer's mind, getting in the way of truly good practice.
Chapter 3 considers the classic moth "Always Comment Your Code".
It is commonly believed, commonly by less experienced programmers, that we should always comment our code. However, it is far better to create code that does not need commenting.
