Asynchronous JavaScript Deep Dive

在JavaScript中有效地使用异步代码是使用JavaScript的任何人的一项基本技能。本课程将带您从初学者或中级学习精通异步JavaScript。

我首先讨论JavaScript中的异步代码及其与同步代码的比较。我们来看一下事件循环及其在异步JavaScript中的作用。然后，我们查看并使用原始的异步模式（回调）。我们深入研究Promises，并深入解决这个问题。然后，我们在讨论中添加异步等待模式。在上一节中，我们介绍了生成器以及如何以及何时在代码中使用它们。

Requirements

A basic level of JavaScript. The more experience you have the more easily you will grasp the concepts taught in this course.
A desire to master callbacks, promises, async await and generators.

Description

Effectively working with asynchronous code in JavaScript is an essential skill for anyone working with JavaScript. This course will take you from a beginner or intermediate level to mastering asynchronous JavaScript.

I start with a discussion of asynchronous code in JavaScript and how it compares with synchronous code. We take a look at the event loop and the role it plays in asynchronous JavaScript. We then look at and work with the original asynchronous pattern, the callback. We dive into Promises, and tackle this subject in depth. We then add the async await pattern to the discussion. In the last section we cover generators and how and when they can be used in your code.

I’ve built the instruction with numerous examples. I also provide all the code files so you can follow along and experiment on your own. The course includes 10 exercise and one quiz in order to give you plenty of opportunities to apply the concepts taught.

By taking this course you will be able to:

Use callbacks throughout your code.

Incorporate and work with promises no matter the source.

Use the async await pattern to make your asynchronous code easier to reason about.

Incorporate generators when needed.

This is one of the best courses I’ve produced, and I feel is unmatched in its coverage of asynchronous JavaScript. If you are looking to learn this very important topic, I would love to take this journey with you.
