Quick Answer
AJAX-heavy apps: use a central AJAX manager to deduplicate requests, use $.ajaxSetup for global defaults (headers, timeout), handle errors globally with $(document).ajaxError(fn), show a loading indicator with ajaxStart/ajaxStop, use promise chaining for dependent calls, and abort previous requests with xhr.abort() when starting new ones for the same resource.
Answer
Use .load(), $.ajax(), $.getJSON() for dynamic updates. Ensure error handling, caching, and loading indicators. Keep DOM updates batched for performance. Enables SPA-like behavior with minimal reloads.
