Functional Programming - 22: Functor

[@nathaaaaaa]

I had to rewatch many of your videos multiple times to get through it. I watched many yt videos on functors and read a bunch of stuff, and now it finally makes sense. Last week I've been following Tsod's stream on building a JSON parser with combinatorial parsers from scratch in Haskell, the "fmap" parts were sort of a black box to me. I had in my mind that it was used to map one value that was "inside" a thing to another (Parser a -> Parser b), but I couldn't understand how it worked and why it was built that way. Now I do. Thanks for those videos, if I ever manage to have a working parser on the thing that I am building you and Tsod are the reason for it.

I’m glad that my videos were helpful to you. I’m not familiar with tsod. Can you please share a link?

@@webvv Fantastic series! I really like it! I think he meant "Tsoding daily" - He streams on twitch and has a YT-channel here aswell.

I read the most adequate guide book but I didn't get much. When you show about arrow composition it suddenly enlightened my mind. Thank you for your well explanation.

[@webvv]

I’m really happy to hear that you find this video useful. Stay tuned for more.

These videos are great. I'm really looking forward to you explaining HKTs in typescript as they are something I still struggle with.

[@webvv]

I’m glad you like the video. I’ll go through HKT in the next couple of videos.

Thank you so much! I think your videos are a great combination of theory and practice which helps me to get a grasp on the subject!

[@webvv]

I’m glad you like them.

Thanks for your clear explanations!

Glad it was helpful!

Real nice job Sahand! :)

Happy you liked it :)

I do not understand much, I'm just getting into functional programming any suggestions from this series or any other out there?

[@webvv]

Any parts you need me to explain more? Let me know, I try my best to explain it here. I’ll also create a demo video on Functors. Maybe that could help clarify some of your questions.

[@imperfect_analysis]

Rigorous. Thank you. Other courses felt a lot less rigorous to me this is clear and well defined Edit : why type script 😢 Haskell would do it

[@webvv]

I chose TypeScript because I felt FP deserves more attention and awareness among JavaScript and TypeScript community. But I agree! It’s much easier to explain things like Functor in Haskell.

Thank you bro!=)

[@webvv]

Thank you for watching bro

[@ICopiedJohnOswald]

Functional programming is not based on Category Theory. Haskell takes a lot inspiration from CT but that is one specific functional language.

[@ecMathGeek]

Do you have a reliable resource or counter example to justify this statement?
