Comment code
Do not keep code in comment.
Do not be afraid to lose the old code: Old versions of your code should be in the source control.
If the commented code is for your own tests it must remain on your Local environment, at the end of the tests delete the commented code which is no longer useful before checkin/commit.
Use comments to explain not to ignore; make your comments useful and don’t repeats what the code itself says.
Don't commit/push commented code
