Welcome to Programmer Humor!
This is a place where you can post jokes, memes, humor, etc. related to programming!
For sharing awful code theres also Programming Horror.
Yes, someone actually did this and I found it running on our server
You want to expand your business to Europe. Bam, your code is broken, in Europe the week starts on Monday.
Than you want to expand to the middle east. Bam, broken again... Because in arab countries and Israel, the weekend is on Friday and Saturday.
Then you want to expand to Mexico and India. Bam, broken again, their weekend is only on Sunday.
The obvious solution is to inject an IWeekendDaysOfWeekProvider service in the inversion of control container. In your, uh, javascript web app.
Just npm install isWeekend for the required locales.
Depends on: isMonday, isTuesday,...

I was wondering why the second example returned monday and tuesday. I had no idea the week could start any day other than monday
Honestly the first one is the only one that works when people define the first day of the week differently. On the other hand, it does make you wonder. If Sunday is the first day of the week (as it is in many places) then how is it also part of the weekend?
But if you're worried about locale, you can't assume people use the string "Saturday" to describe Saturday either. That solution only works in English.
I assume this is in a language where the first day of the week is a fixed part of the language (like JS).
Yeah it's the front end of the week and Saturday is the rear end
They're the week's ends, front and back.
Thats not really one weekend then though, is it? Its more like last week’s post-week weekend and this week’s pre-week weekend
Ok another US local units are retarded rant: it's called weekEND! why do you start your week at sunday and not monday! Sunday is part of the weekEND!
If you're referring to an "end" of an object, it can refer to the extreme of a side of it. For example, aglets are at either end of a shoelace.
I'm refering to end in a temporal sense because we are talking about a time context here. There is a clear direction so going backwards brings you to the begin.
weekend = day_of_week in (“sat”, “sun”)
As a bonus this completely sidesteps the issue of what day is 0 or 1.
Until some idiot sends in "Sunday" as days of the week...
Why would you call it weekend and the start the week with half of it?!
A rope has two ends, and so does a week
Sentences have both meanings and sound, yours have sound
I like fancy insults
Methinks your username is a little too relevant right now :p
Do you say weekend or weekends?
I'd make it a named function for clarity and testability and proceed to give zero shits how it is implemented. I would unironically write this code if it worked, but I wouldn't inline it to reduce the cognitive load of reading it.
This, and maybe a couple of unit tests
You forgot weekend = dayOfWeek.name[0] == 'S';
Interesting that your days are 1-indexed. What happens on nullday?

[Paneled meme with a brain that gets increasingly glowing]
[The brain is smaller than the skull]
if dayOfWeek.name == "Sunday" || dayOfWeek.name == "Saturday"
weekend = true
[The brain is glowing in some areas]
if dayOfWeek < 2 || dayOfWeek > 6
weekend = true
[The brain is shooting out rays of light]
weekend = !((dayOfWeek - 1) % 6)
