What you will learn

Once you have completed this course, you will be fully capable of writing your own applications that take advantage of the core.async library.

Learn the basics of core.async


Description

In this Communicating Sequential Processes with core.async training course, expert author Timothy Baldridge will teach you the basics of core.async. This course is designed for users that already have a working knowledge of Clojure and ClojureScript.

You will start by learning how to create channels, then jump into creating and using threads. From there, Timothy will teach you how to combine and split channel streams, work with transducers, and the pipeline abstraction. This video tutorial also provides a quick tour of core.async internals, including how channels are modeled, how alt handlers interact with channels, and how threads interface with channels. Finally, you will learn about non-blocking channel operations and how to put it all together.

Once you have completed this computer based training course, you will be fully capable of writing your own applications that take advantage of the core.async library.

A thorough overview of all aspects of core.async, However, I can confirm that a good foundation in Clojure fundamentals is definitely recommended for the student, to get the most out of this course. The instructor presents the concepts in a well organized sequence of concepts.

good, but would like to see some images to help illustrate some of the concepts. Code is king, but a few pictures here and there are gold. Stephen Grider's lessons on udemy are a perfect example of a great balance between code and diagrams.

O professor tem um profundo conhecimento de Clojure e da lib core.async. Os vídeos são curtos, porém claramente explicados e com exemplos bons. Recomendo!

As suggestion, I think the close caption has some issues with some words. In addition, I think it can add spanish caption.

The course is very good with direct to the point explications and examples. It's also quite advance and requires some familiarity with Lisp and functional thinking but with a little effort I think can be useful for beginners too. It's amazing that core.async offers a set of tools that can replace with ease stuff that many javascript frameworks like react or angular provide in a more verbose way. It would have been even better if the couse it would have focused also on more real life cases like design patterns for handle an event base feature or things like that.

I couldn't find such a well presented information on core/async in other courses/books. The explanation on transducers, despite not being exactly part of the content, way worth 5 star itself. Presenter is very clear and direct.

I couldn't find a good tutorial for core.async anywhere. I saw this course and thought I'd give it a shot, and I'm very glad I did. It's very easy to understand and quite enjoyable to watch

Fantastic course - the instructor is the most enlightened human being on earth :-) I am a clojure newbie, but a fairly experienced programmer (c#, c++ etc) I am right now midway through the course, but not only did I learn a whole bunch of stuff about core.async, but a number of light bulbs went off wrt functional programming, clojure syntax, multi-threaded programming and so on. At the discounted price of $15, this is a steal.

Timothy is great at explaining the content--no wonder, since he's the developer for Clojure's core.async!
