Quick Answer
Handle multiple AJAX calls: run them in parallel with $.when(call1, call2).done(function(r1, r2) {}) - waits for all. For sequential calls: chain .done() callbacks. Use a request queue for serialized execution. Abort stale requests when new ones start. Show a global loading indicator with $.ajaxStart/$.ajaxStop and a counter to track concurrent requests.
Answer
Use $.when() for parallel calls. Process data after all calls complete. Useful for dependent UI updates and consistent state.
