Functional Programming in JavaScript: A Practical Approach (Udemy.com)

The code samples really need to be tidied up. Should be using fat arrow functions instead of function expressions for the callbacks. Should remove all 'var' declarations and also either use 'let' everywhere or use 'const' everywhere instead of seeming to use them at random. This is demonstrating very poor coding practices to beginners

This was a great course. The curriculum revolves around a definition of functional programming (by Eric Elliott). The instructor breaks down that definition into its component pieces, explaining each piece and showing how it fits within the wider context of the definition. I felt that this approach was very focused and helped me gradually build up my understanding of the topic. The instructor is great at explaining and demonstrating concepts slowly. The exercises build on previous exercises in this course, which means you can see how the code gradually turns more 'functional' as you progress. You will have an easier time with this course if you understand core JS concepts, like JS objects, closure, JS execution contexts... Highly recommended!

A very good introduction into functional programming. The course is well structured and builds up step by step. It helps me to understand the concepts ans shows how to realize the example by pure JavaScript and additional libraries Loadash and Ramda. The examples are very well explained.

So far so good. Definitely starting by defining it properly - which is something that lacks when I've tried to approach this subject. Half way - still good, but has lost some of the conceptual guiding force. Seeing a lot of techniques ( which are interesting ) but I've lost track of why I'd want to do this, is it the best way to do something, and why it still relates to functional programming.

This course is really amazing for beginners! Not as good for experienced programmers though because explaining basic JavaScript concepts (that should be well-known for experienced programmers already) takes a great amount of time. Some of the examples might seem a bit outdated in 2020. But the basic functional programming concepts are explained very well!

Over all very good refresher on functional programming and some of its aspects using JavaScript. However, at times, examples were a little too involved, some were contrived and relied on pre written external code and lacked coherent explanation. The structure could be improved using more modern techniques and tooling, perhaps moving away from reliance on browser console and using node more and the strengths of the v8 engine. Syntax could also do with improving, lots of strange uses of things. However, good instructor and examples in places, would recommend.

I have been working with JavaScript for a while, but always found myself struggling with concepts of functional programming. Most of the other courses just blazed through the functional programming part. But the instructions laid down by Steve finally allowed me to unlock doors and concepts that eluded me all along. I am so glad i have had an opportunity to subscribe to Steve's Functional Programming and Asynchronous Programming courses. They now top my list of go-to courses for understanding JS concepts. Steve, I am looking forward to being a part of your other courses. Thank you.

I came into this course with an understanding of functional programming in JavaScript and saw that it was listed as Intermediate level. It took a while to get to topics that were new to me, such as currying and function composition, but once there I started to get value from this course. I think this is most valuable to those who are completely new to functional programming and the concepts of immutability. For someone who is already familiar with cloning, immutability, and filter/map/reduce, this course is a bit too elementary.

Takes difficult to understand concepts and delivers them in an extremely easy to digest format. Many other online resources get theory heavy too quickly. This material moves at a manageable pace. I really learned a lot through this resource and strongly recommend it.

Good overview of Functional programming concepts. The instructor provided clear instructions on the cover concepts. All examples worked as expected. I would recommend this course if you want to get a good overview of function programming concepts.
