Even shorter, it's 43 characters now (the top line only). Output is the array F.

for(a=0,F=[b=1,1];a++-20;)F[a+1]=b+=F[a-b]

Oh, thank you! That's even shorter

Kudos for the write-up. I like that I can see the result of the code in each revision
u/BirdsTweetCodersDweet

Yeah, these write-up tutorials showing the step-by-step changes in the code are amazing... Thanks!
