Asynchronous JavaScript
Overview
Asynchronous programming is crucial for handling tasks like fetching data from servers, making API requests, or performing time-consuming operations without blocking the main execution thread.
The objective of this learning activity is to
- Understand the basics of asynchronous programming in JavaScript.
- Learn how to use the
asyncfunction andawaitkeyword to manage asynchronous operations. - Explore error handling mechanisms with
try...catchblocks in asynchronous functions. - Practice using async and await with real-world examples.
"Asynchronous programming is a technique that enables your program to start a potentially long-running task and still be able to be responsive to other events while that task runs, rather than having to wait until that task has finished. Once that task has finished, your program is presented with the result." - MDN
