Quick Answer
Large production jQuery best practices: minimize jQuery version fragmentation (one version per app), audit unused plugins (each adds weight and risk), use Content Security Policy to prevent XSS, implement subresource integrity (SRI) for CDN scripts, monitor Core Web Vitals (jQuery can hurt TBT if heavy scripts block rendering), and document all non-obvious jQuery patterns for the maintenance team.
Answer
Use delegation, caching, and namespaced events. Modularize using plugins and IIFE. Clean up events and timers. Optimize DOM, AJAX, and animations. Use jQuery only where beneficial.
