The fetch API provides a more streamlined and modern interface for making requests, while XHR has built-in support for handling uploads and progressive tracking.
Handling upload errors, providing visual feedback, and ensuring secure and smooth uploads are all crucial aspects of a good file upload implementation.
Demonstrating how to implement enhanced user interfaces and best practices for error handling, this guide provides a solid introduction to asynchronous file uploads in JavaScript.
By following these guidelines, you’ll be well-equipped to implement robust asynchronous file upload functionality in your JavaScript applications.
