Commenting code is a super important habit to get into—it not only helps others understand your thought process but also makes it easier for you to pick up where you left off if you revisit the code later. Plus, well-commented code can significantly reduce the onboarding time for new developers on a project. Remember, comments should explain the “why” behind the code, not just the “what.” For instance, stating why you chose a particular algorithm or data structure can be far more helpful than just labeling it. According to a study by SmartBear, 44% of developers regard poorly documented code as a top cause of project delays, so it’s definitely worth the extra effort!

Curious: how do they know that? Recorded history is like 5k years right?
