I think they’re only talking about JavaScript, in which case the forEach function doesn’t return anything. So you can do x.map(…).forEach(…) because map returns an array. But u can’t do x.forEach(…).map(…) Ur examples seem like they’re for a different language.

I kind of agree. At least, that's generally the way I prefer to do it. But I find I'm most creative when I'm working with other people, as long as I like working with them. They just always have ideas, and things to add to my own ideas, that I could never reach on my own.

John Cleese has a great video on this: https://www.youtube.com/watch?v=Pb5oIIPO62g

Cleese's talks on this are good, personal faves, and have useful advice. But they're also oriented to a specific activity: developing comedic scripts. I'd be somewhat cautious in overgeneralising.

Again, not that there aren't useful concepts, and his anti-creativity measures strike me as valid.

Sometimes the reviews also don't match the rating. I see this happen all the time, not only on Amazon: "Great service, great product. No complaints." 1 star

I confronted someone who left this sort of my review on my mobile app to ask why they gave me one star if they were so pleased. It was the only review under five stars.

They said that they wanted their review to appear in the "top negative review" column since it didn't have a shot at the "top positive review" column.

I was dumbfounded.

I had a similar story - user said that even though their review is wrong, "I'll let it stay because I don't feel like changing it".

Really makes you question what is going on in the heads of people around you.

I noticed my ex-girlfriend rating our Uber driver 3/5 stars once we arrived at the airport. I asked her what was wrong with him. She said he was fine but it was just an average ride, nothing exceptional. And that she's only given out one 4/5 and zero 5/5's.

Not her fault. What choice do you have but to assign your own arbitrary meanings to each star, and how aren't those going to vary from person to person?

I never looked at 5-star rating systems the same.

I agree it's frustrating that most sites leave it up to each individual user to decide what each star rating means.

On the other hand, I don't think it's really a problem as long as users are consistent. It doesn't matter how "harsh" they are as long as everyone has similar odds of getting a harsh reviewer.

I do tend to leave slightly below-average ratings because I like leaving room for truly exceptional products/experiences to get a higher rating.

I used to see this very commonly on a site with a dropdown rating system. I believe people were selecting 5 stars and then trying to scroll down the page. Since they'd be focused on the dropdown it'd change their rating to 1 star. That was my hypothesis anyway.
