Advanced Asynchronous JavaScript

• Gain a deep understanding of advanced asynchronous programming concepts in JavaScript, with a focus on Observables and their implementation.
• Learn how to build complex asynchronous applications using Observables, including the creation of custom operators like map(), filter(), and reduce().
• Understand how to manage and manipulate data streams, convert events into Observables, and handle multiple subscriptions efficiently.
• Explore real-world problem-solving techniques, such as creating smooth animations on low-end devices and building an image viewer application.
• Master error handling in asynchronous code, including the use of catch() for specific errors and strategies for canceling promises and subscriptions.
• Delve into debugging and testing Observables, ensuring reliable and maintainable asynchronous code.

This advanced course on asynchronous JavaScript, led by Jafar Husain, takes you beyond the fundamentals to explore more complex concepts and techniques. The course focuses on Observables, a powerful tool for managing asynchronous data streams, and teaches you how to implement them effectively in real-world applications. Through hands-on exercises, you’ll learn to create custom operators, handle errors, and build efficient and scalable applications.

• JavaScript developers with an intermediate understanding of asynchronous programming.
• Developers who have taken the "Asynchronous Programming in JavaScript (with Rx.js Observables)" course and want to deepen their knowledge.
• Engineers looking to optimize performance and manage complexity in large-scale JavaScript applications.

• Intermediate knowledge of JavaScript, including functions, loops, objects, and function scope.
• Prior experience with asynchronous programming and familiarity with Observables.

Introduction to Advanced Observables
Learn about the changes in the Observable interface and build a minimal implementation, exploring how Observables, Observers, and Subscriptions work together.
