What are the differences between Fetch API and XMLHttpRequest?
An example of an AI chatbot conversation about Fetch API vs XMLHttpRequest.
What are the differences between Fetch API and XMLHttpRequest?
The Fetch API is a modern interface for making network requests, while XMLHttpRequest is an older technology. Fetch uses Promises, making it easier to work with asynchronous code, whereas XMLHttpRequest uses callbacks.
Can you give me an example of how to use both?
Sure! For Fetch API, you can use fetch('url').then(response => response.json()). For XMLHttpRequest, it looks like this: var xhr = new XMLHttpRequest(); xhr.open('GET', 'url'); xhr.onload = function() { console.log(xhr.responseText); }; xhr.send();.
Which one should I use for new projects?
It's generally recommended to use the Fetch API for new projects due to its simplicity and better support for modern JavaScript features.
Are there any limitations of the Fetch API?
Yes, Fetch does not support progress monitoring for uploads and downloads, and it does not automatically reject the promise on HTTP error statuses.
