Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
This is a mistake. In fact, you are right: observables are push systems. I have already corrected it. Thank you very much for the comment.
In the beggining bit THANK you for prepering this exercises.
My question is regarding this part of sescription:
"and lazy pull computations"
lazy yes, but is it really pull ?
pull is Iterator, push is Observable..
Or you mean something diffrent.
Thank you
