Refactor a Promise Chain to Function Composition using Ramda

Promise chains can be a powerful way to handle a series of transformations to the results of an async call. In some cases, additional promises are required along the way. In cases where there are no new promises, function composition can reduce the number of dot chained thens you need. In this lesson, we'll look at how to take a promise chain, and reduce it down with function composition.

I've watched a lot of videos about Ramda, and now that I'm starting to understand the concepts I found this video very informative and it's great to finally see a real life example on how you would use Ramda to improve your code, thank you :)

This is a really good demonstration! I switched to using Ramda a few months ago and I still think it's awesome!

Ramda is so sleek, I'm gonna start using it along with RxJS. Thanks for the video!

Short and to the point . I like this compact and to the point style of teaching...!!! THanks Andrew!!

use async/await to get rid of the thens ^^

Can you please post the full URLs used in the examples? Thank you!

This style is great for the happy flow but what about error handling?

[kettlebellsporttraining]

Really good example of some useful functional programming in Js, thank you! Anyway, when dealing with side effects (fetch, dom etc..) you should perhaps consider using monads which help in handling error cases, async operations and so on while still being compositional
