About This Episode:
Before fetch() became the go-to for making network requests, developers had to rely on XMLHttpRequest (XHR) — and later, jQuery’s $.ajax() — to bring data into web pages dynamically.
In this video, we’ll explore:
- The basics of making a request with XMLHttpRequest 🏗️
- How jQuery simplified AJAX calls 📦
- The key differences between XHR and Fetch
- Why modern JavaScript has left XHR behind in favor of cleaner, promise-based APIs ✨
Understanding this history will give you context for legacy codebases 👴 and help you appreciate just how much easier today’s tools make things.
👉 Watch now and see how far we’ve come with AJAX and Fetch! 🚀
