not sure how im going to detect nested describes/it ’s though…. ill need to puzzle that one out :slightly_smiling_face:

When you do (make-vector 100), are the values always set to 0 by default? I can’t seem to find anything in the documentation.

Yes

Cool thanks

@mark.warren https://docs.racket-lang.org/reference/vectors.html?q=make-vector#%28def._%28%28quote._~23~25kernel%29._make-vector%29%29

Is there a way of updating multiple keys at once in a hash?

@stefan.kruger You can use hash-union

https://docs.racket-lang.org/reference/hashtables.html?q=hash-union#%28def._%28%28lib._racket%2Fhash..rkt%29._hash-union%29%29

That will do nicely! Thanks

@stefan.kruger also hash-set*

Oh that’s better, I forgot about that one

So many times when I ask the question, “I wonder if Racket …?”, the answer is “of course”, so I’ve come to expect that the thing I’m looking for exists :slightly_smiling_face:

I’m discovering this, too! The library is vast. But the challenge is finding it, as a n00b. This Slack has accelerated my learning.

@samth Thanks, my doc fu needs improving :grin:
