Recently, I asked my Twitter followers what they considered to be the most complex topics in JavaScript. The response was overwhelming, with over 200 replies pouring in. After analyzing the feedback, there were several concepts that stood out as particularly difficult for many developers to grasp. These concepts include:

  • this
  • Asynchronous JavaScript (promises, callbacks, async/await)
  • Closures
  • The event loop
  • Recursion
  • Scope
  • Hoisting
  • Prototypical inheritance
  • bind(), call(), apply()
  • reduce()
  • Generators
  • fetch()

Except for generators, which are more specialized, these are all concepts that we encounter on a regular basis in JavaScript programming.

To address the complexity surrounding these topics, I have written articles on each one on my blog. You can easily find them by using the search bar. However, I asked this question not only to provide resources but also to gather insights for a new course that I am preparing called The JavaScript Course. This course aims to be a comprehensive and high-quality learning experience, scheduled for release in November.

The course will start with the basics of JavaScript to ensure that beginners can follow along. However, it will quickly progress into more advanced and challenging topics. My goal is to cover everything that has been identified as confusing by the JavaScript community.

In designing this course, I am taking a unique approach. It will be structured similarly to a course I previously offered in 2019, where participants received daily emails with questions and challenges. The course will span 4 weeks, with a new lesson unlocking each day from Monday to Friday. The content will be presented in a fun and interactive manner to keep learners engaged. Each email will encourage action, as I believe that consistent practice is crucial for learning. My aim is to create an active learning community where participants can interact and progress together.

To facilitate this new learning experience, I have developed a dedicated course platform. I am confident that it will enhance the overall learning journey.

Of course, having a supportive community is essential for events like this. Therefore, I will ensure the course is accompanied by a vibrant community where participants can connect and support one another.

All the challenging topics mentioned above will receive special attention in this course. I hope that it proves to be the key that unlocks a deep understanding of these concepts for all participants.
