If you’re not certain then this Asynchronous JavaScript course is perfect for you.


Understanding the asynchronous nature of Javascript is key to mastering the language.

This course is designed to take someone with a beginner level knowledge of async programming and turn them into an expert.

We do this by starting off very simple, explaining the core concepts.

Then step by step adding in layers of knowledge, punctuated by quizzes and coding challenges to cement and your knowledge before moving onto the next section.


I promise you’ll end this course an expert in asynchronous programming in JavaScript, with knowledge most other experts don’t even have.

You’ll ace any JavaScript interview questions related to asynchronous code.

You’ll spend less time chasing down bugs in async code.

3You’ll amaze your colleagues and friends with your level of knowledge and expertise in async programming.


I will explain what async and sync code really is, the advantages and disadvantages of each.

We’ll cover in-depth the various asynchronous patterns in JavaScript including Callbacks, Promises, Async/Await and even Generators with plenty of exercises to practice what you’ve learnt.

In the end we’ll go deep into the event architecture itself,  you’ll know how async code is actually implemented in these applications.


The ideal student for this course is someone with at least a basic level of Javascript, you must have written a few apps already.

You’ll also need some familiarity with node and be comfortable on the command line.

But everything else I will explain from first principles.Who is the target audience?
