Note: Some of the RxJS syntax used in this course is outdated, but the concepts taught on arrays, async, and observables are still reliable and applicable.

Async programming may seem daunting. How can we write programs that accept user input, run animations, and send server requests over the same period? How do we keep the code clear and concise? How do we gracefully propagate and handle asynchronous errors? How can we avoid memory leaks caused by dangling event handlers? JavaScript's loops and try/catch keywords are no help - they only work on synchronous functions.

Here's the good news: Asynchronous programming is much easier than it seems. The key is to think differently about events. It is possible to build most asynchronous programs using a handful of simple functions. We will learn why most JavaScript developers approach asynchronous programming the wrong way, and how to avoid these common mistakes.

    What did you like about this course?

    This is one of the best tutorials i have found on RxJs , observables . You have really gone to the core of it from basic array operations to advanced async operatations . Thank you so much for this great content.

    What did you like about this course?

    great, would it be possible to update it to the new Observable api, it uses .subscribe now, and pipe?

    What would make this course a 7 for you?

    It's a really good course, I'm only not rating it a 7 because it would be nice to continue on and learn more about async programming using observables. This course feels like a fantastic primer but it would be nice to have something much more in depth, like the one on front end masters. Especially as there aren't many new courses on the topic. Thanks :)
