When you see a comment that says exactly what the code says, remove it.
The purpose of code is to explain to other programmers what you want the computer to do. Comments and code present different trade-offs for you as a writer and for future readers. You can explain anything you want in prose. On the other hand, there’s no mechanism to double-check the accuracy of prose as the system changes, and comments might become redundant as the code evolves.
