FS2: Typed Functional Streams in Scala

[@arminkeyvanloo1151]

Been wondering when you'll get to do some of your quality work on fs2. Can't wait for more advanced fs2 vids.

[@no_more_free_nicks]

Thank you for this video, it is the best and quickest introduction to Fs2. I have a taks based on this library to be done a week ago.

[@JeetBanerjee23]

Thanks so much for this, been waiting for FS2 tutorial since so long. Looking forward for the part 2 (and more) videos explaining the advanced fs2 concepts too.

[@nayak232]

I couldn’t help but notice that the debug function is not pure, but has side effect in it. Not that it matters for the demo. Thanks for your video. 😀

[@rockthejvm]

It's for demo purposes and does not "stain" the IO chains, because we process IOs, which themselves wrap potentially impure computations.

Thanks for this content!

[@TheHangoverer]

I love your scala tips

[@mattygrows7667]

you should do one on ZIO streams too

[@BloodnutXcom]

it's pretty identical

Great video

[@miguelgarciapuyol2313]

You rock!

5:52 can you @Daniel tell as what hot keys you've used for block selecting please?

[@rockthejvm]

I'm on a Mac, so I hit Option-Option(then hold), then arrow keys or Shift-clicks for multi-cursor.

[@kaktusdono]

For linux and i guess Windows as well block-selection is shift+alt+mouse movement, multi-cursor is ctrl-ctrl + arrows

[@mbesida]

Why is that called Pure type? AFAIK cats lib has Id type for that same purpose

[@rockthejvm]

Yep, Id works in the same way. Pure is used for covariance reasons.

[@leorandomnickname]

what is an example of an existing real-life application of this

[@rockthejvm]

Any backend where your data comes asynchronously.
