Daniel Silva If you think you can comprehend your code without comments, it is fine to omit them.

However, we have to consider those who are not programming-savvy. Our comments should also make it easier for beginners to understand what we are doing.

Comments are there to describe the intent of the code (ie, what it is for), not paraphrasing how it is done in code( clean code is self explanatory).
