Quick Answer
AJAX-heavy app patterns: central request manager (deduplicates, caches, aborts stale requests), global error handling with $(document).ajaxError(), loading indicators with ajaxStart/ajaxStop, request queuing for dependent calls, response caching in a Map with TTL, and CSRF token injection globally via $.ajaxSetup({headers: {"X-CSRF-Token": token}}).
Answer
Use $.ajax(), $.getJSON(), or $.post() with proper error handling. Cache selectors for newly added content. Use promises or deferreds for dependent async operations.
