Developers who have spent any time on large projects understand the importance of code comments. When you’re building many features into the same application, things tend to get complicated. There are so many data bits including functions, variable references, return values, parameters… how are you expected to keep up?
It should come as no surprise that commenting your code is essential, both solo and team projects.

That's not what comments are for... That's actual documentation.
Comments are for those times you can't express yourself very well in the code itself: it says why you did something a certain way, for example.

Agreed. Documenting every bit of the code is more useful than cryptic, embedded comments. We're not obliged to read the manual but if it has been well written it should explain everything.
How often I fall victim to the copy/paste merchant who forgets to modify his comment for the new scenario.

Design and implementation documents? Yes a radical idea which has not gained sufficient traction in all quarters.

1. I name my methods carefully but always add method comments to ensure no ambiguity and misunderstanding of the name (Does "persist" or "store" mean the same thing? Depends...). This also provide a nice intellisense experience
-> I comment for others in my team
2. I comment gnarly code that I can't (or let's face it, don't have time to) rewrite properly. Maybe it's non-obvious, maybe it's temporary, maybe it's because there's a bug in the framework we're using that needs an odd workaround
-> I comment for those reviewing / maintaining the code / my future self who will need to fix it.
3. For code I'm making public I add comments to help newbies walk through it. It's educational code, not lean-and-mean code that needs to save every byte of comment space it can (is this even a thing?)
-> I comment for those looking to use my code
4. Sometimes I comment an exhausting / annoying piece of code with a snarky and what seemed humourous-at-the-time comment.
-> To future palaeontologists who stumble across my code. I hope it makes them grin.

While looking on the aspect of Leads and Managers, A good code will surely have comments with them not only for their recognition but also for the future newbies who place their hands on the code.
As well as of direct use to any programmer reading the source code, comments are sometimes processed in various ways to generate documentation external to the source code itself by documentation generators, or used for integration with source code management systems and other kinds of external programming tools.
The flexibility provided by comments allows for a wide degree of variability, but formal conventions for their use are commonly part of programming style guides.
Too much comments is also not encouraged.

Real Programmers don't comment their code. If it was hard to write, it should be hard to understand.

Newbies will not be working with my code, so in my world, your argument doesn't pan out.
In my world, good code doesn't "need" comments.

Sometimes it's not the code that requires explanation but some quirk of the business logic behind it.

In that case, you need comments right?
|

Our shop documents the business process outside the code base about 99.9% of the time, and this is for the complex business processes. We don't use our code base to document code.
Besides, you are not allowed to even look at our code, until you have read the business docs, design docs, etc., and understand the overall system.
So, we use comments in code....about .1% of the time....and it is not a "need".

The robot overlords are presumably bright enough to understand my code even without comments, and by the time the paleontologists take an interest in me or my code, I expect to have been long retired.
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.

Who do you write comments for? really? Is this noob hour?

Judging from the comments I've read over the past six years, no, it's not noob hour, it's a noob age...

One thing I love about polls is that you start with an expectation of what the answer is and watch as you're proven wrong.
Open your mind a little to the possibility that what you feel is self-evident may, in fact, be not.
(And while you're at it you can put your money where your mouth is[^]  )

Apparently, you don't have knowledge about research and polls. Information you don't care is valuable for researchers. I didn't know that until I've worked for a research company, you'd be surprised the statistics they generate from simple answers...

In earlier time comments were written to enhance the LOC counter.

Just like some of the formatting rules requiring even rather simple statements such as
if (x<0) y=0;
using brackets on their own separate lines and a blank line after it:
if (x < 0)
{
y = 0;
}
<blank line>
That increases your productivity by a factor of five!
