jQuery widgets — tabs, modals, tooltips, carousels, sortable tables, pagination — follow common patterns: ARIA attributes for accessibility, event delegation for performance, and data attributes for state. Package repeated patterns as jQuery plugins.
// jQuery widget pattern checklist:
// [x] ARIA roles and attributes (role, aria-expanded, aria-label)
// [x] Keyboard navigation (Enter/Space to activate, Escape to close)
// [x] Focus management (trap in modal, restore on close)
// [x] Event delegation (parent.on("click", ".child", fn))
// [x] Custom events ($.trigger("widget:action")) for extensibility
// [x] Data storage ($(el).data("state")) for widget state
// [x] $.fn.pluginName() pattern for reusable widgetsWell-built widgets encapsulate state, expose a clean API, and fire events — they are mini-frameworks.
