You have the Node Elephant repository here! ;)
with quasi all nodes explained!
French / English : https://moiscript.weebly.com/biblio-elephant.html

But you have the Transform / Array / Grid
just take care of the start module! :)
here 4 objects...not a big deal ...maybe 5 seconds!



And maybe also the Flow function can makes something after! ;)
