AJAX (Asynchronous JavaScript and XML) revolutionized web development by enabling web pages to request and receive data from servers without full page reloads, creating dynamic, desktop-application-like experiences in browsers. While the term originated when XML was prevalent, modern AJAX typically uses JSON and has evolved with new APIs like Fetch, but the core concept of asynchronous client-server communication remains fundamental to modern web development. Our AJAX articles explore patterns for effective asynchronous web development. Learn about the Fetch API and XMLHttpRequest, handling asynchronous operations with promises and async/await, error handling for network requests, and managing loading states for better user experience.

Discover approaches to API integration, handling CORS issues, implementing retry logic and request cancellation, and optimizing request performance. Explore patterns for real-time updates including polling, long-polling, and when to use WebSockets instead, managing request concurrency, and security considerations for client-server communication. Whether you're implementing API integration, building single-page applications, or creating interactive interfaces, these resources provide practical guidance for asynchronous web development techniques.
