Accessible Javascript patterns
summary
Shows working code (GitHub and demo links) that replaces slow tab-only menus with an arrow-key and character search navigation: Enter simulates a click, Down/Up open popups from top or bottom, Left/Right move top-level items, Escape exits. Presents a reusable focus-trap dialog class that supports open/replace modes, restores focus targets, and warns to remove event listeners on teardown. Tests use Lighthouse, WAVE and pa11y; core code comes from W3 examples translated to ES6.
