Excellent video! Thank you for this helpful content. Would love to see more complex flows, i.e. multiple predicates

Best tutorials on YouTube. I hope MrFunctor gets popular. Would like to see him code in different functional languages / libraries.

I've worked with fp-ts the past, but our team only took advantage of the Either type. The rest of fp-ts seemed to be too scary for us. I've been enjoying this series because of how useful it's been. I'd love to see examples with more complicated data types like promises or API responses
