Note: Some of the RxJS syntax used in this course is outdated, but the concepts taught on arrays, async, and observables are still reliable and applicable.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.
A Community Resource means that it’s free to access for all. The instructor of this lesson requested it to be open to the public.
Very clear explanations with good practical examples. The pace of covering the material also was just right! Thanks Jafar!
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.
Good balance between speed and explanation.
great, would it be possible to update it to the new Observable api, it uses .subscribe now, and pipe?
The pace and the way of teaching is great. Thanx for the course.
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 :)
Become familiar with the Workers CLI wrangler
that we will use to bootstrap our Worker project. From there you'll understand how a Worker receives and returns requests/Responses. We will also build this serverless function locally for development and deploy it to a custom domain.
This is a practical project based look at building a working e-commerce store using modern tools and APIs. Excellent for a weekend side-project for your developer project portfolio
git is a critical component in the modern web developers tool box. This course is a solid introduction and goes beyond the basics with some more advanced git commands you are sure to find useful.
