JavaScript Skills for Salesforce Developers

Write Asynchronous JavaScript
Learning Objectives
After completing this unit, you’ll be able to:

Identify important asynchronous features in JavaScript.
Invoke functions asynchronously using setTimeout.
Write and invoke callback functions.
Write and invoke promise-based functions.
Think way back to when we first introduced the JavaScript engine. The engine has a single thread that does work, finishes, then has new work stuffed into it to start over again.

Of course, it’s critical that the thread not be blocked.
