Additional Exercises? #11

Open dougflip opened 5 years ago

dougflip commented 5 years ago

Hello @alpacaaa! First off, thanks for this repo - I've had a great time working through the exercises! I've gone through them once by myself and I'm taking some people at work through who have zero prior Haskell experience. Its been great!

I was curious if you have plans to extend it beyond 8 exercises? If so, is there anything I can do to help? I'm still somewhat of a novice Haskell user but would love to help if possible! Thanks again!

Hey @dougflip! You're right, I should be adding more content :)

Where do you think should the exercises go from here? As a novice, do you think exercises have covered enough for you to feel somewhat productive with the language?

To me, the next big thing would be introducing IO. Have exercises that make HTTP requests or maybe save and read to files.

Thanks for the feedback!

dougflip commented 5 years ago

I was thinking IO would be a neat next step as well. I saw that you already have an effectfulHandler as part of the API. Maybe we could read/write your shopping cart to a file instead of just keeping it in memory? The JS tests would be largely the same I guess - but the backend implementation would obviously be different.

I hadn't thought about making HTTP requests, but that would be really cool too! Did you have any ideas about what service(s) could be used?

alpacaaa commented 5 years ago

Yes, effectfulHandler is already there just waiting to be used! :D Your suggestion of keeping exercises as they are but introduce state is a neat idea. I was thinking of working with random REST apis (fetch posts from Reddit or issues/commits from a repo on Github).

I'll get to it eventually, thanks for the feedback and let me know if you have other suggestions :)

@alpacaaa Hi, wonderful series - thank you for making this. It's very difficult to find project-driven or otherwise interactive learning resources for Haskell; this series is an absolute gem!

I hope to see more exercises, too. I think @dougflip makes a good suggestion in expanding existing material to include more concepts e.g. IO, state, maybe a simple data service layer with a key/value store?

I'd be happy to help (I'm obviously very novice at Haskell, but I can write JS ;-) ). Thanks!

Hi @MatthewZito! I'd love to come back to this project eventually, I'm busy with other stuff and can't give it the attention it deserves. If you have concrete ideas of exercises/small projects you think it'd be interesting to build please post them here! Even if they're written in JS that's perfectly fine :) I'm always on the lookout for more beginner level material to teach Haskell, so ideas welcome.

@MatthewZito just to add something else to the mix - I picked up a copy of this yesterday: https://leanpub.com/simple-haskell-book. You sound like a similar background as me (working in JS but learning Haskell) so you may be interested too :)

@alpacaaa thanks again for your work focusing on simple and practical Haskell. It really is helpful for those of us trying to pick up Haskell on the side!
