Asynchronous Programming: The End of The Loop
|
Learn the concepts of arrays, async programming, and observables in this course. Discover how to write clear and concise code, handle asynchronous errors, and avoid memory leaks. Explore the power of Array methods like forEach, map, and filter, and learn how to chain them effectively. Introduce yourself to the world of Observables and their map method. Dive into advanced topics like drag and drop using Observables. Don’t miss out on this opportunity to master asynchronous programming.
Note: Some of the RxJS syntax used in this course is outdated, but the concepts taught on arrays, async, and observables are still reliable and applicable.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.
