Måns,
First of all: no, we do not define the results of getDay(). Those are
given by said standard javascript function.
I believe both your intellectual and your js capacity do just fine, I
can tell. It's just my sloppy untested proposals which at times need a
second look to turn out right...
So, if getDay() = 0 means we're talking of a Sunday ....and with 1
being Monday ...and a week presumably having some unchanging 7
days ...well then to get weekends, the code must sure read like this:
<<tiddler {{
[0,6].contains((new
Date()).getDay())?"WeekendTiddler":"WeekDayTiddler"
}}>>
My morning sleepiness almost went so far as to write saturday as being
7, but lucky for us, I spared us that bit of confusion, phew.
I guess that's why quality code, above all, requires just as much
attention (1) as it does require know-how ...or rather 'know where to
look for answers for problems to solve' ...and most importantly,
testing (2).
In other words, it can be that simple and you can still get wrong, if
you miss out on those two. :-D
Cheers, tb
