Asynchronous JavaScript

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 achieve this by starting with simple concepts, explaining core principles, and gradually adding layers of knowledge. This is punctuated by quizzes and coding challenges to reinforce your understanding before moving onto the next section.

Why This Course?

If you've ever encountered asynchronous code and wondered, "What went wrong?" then this course is perfect for you. Consider this example:

code
  function doAsyncTask(cb) {
    cb();
  }

  doAsyncTask(() => console.log(message));

  const message = "Hello, I am a teapot";

Can you fix this code without moving the last variable up the page? If not, you've come to the right place.

What You'll Learn

• Ace any asynchronous JavaScript interview question
• Spend less time debugging asynchronous code
• Write fast and performant JavaScript applications
• Understand complex JavaScript concepts

Course Benefits

By the end of this course, you'll become an expert in asynchronous programming in JavaScript, with profound insights that many seasoned developers may not possess.

• Perform exceptionally in JavaScript interviews, especially questions about asynchronous code
• Reduce time spent on debugging asynchronous code
• Impress your colleagues and friends with your comprehensive knowledge of async programming

Course Structure

How We Teach

We will clearly explain the concepts of async and sync code, along with their respective advantages and disadvantages. We'll cover in-depth asynchronous patterns in JavaScript, including Callbacks, Promises, Async/Await, and even Generators, with plenty of exercises to practice and reinforce what you've learned.

Ultimately, we'll delve into the event architecture to understand how async code is implemented in applications.

Target Audience

Is This Course For You?

The ideal student for this course should have at least a basic understanding of JavaScript, having written a few apps already. Familiarity with Node.js and comfort with command line usage is also expected. However, we'll explain everything else from first principles.
