How do you use event delegation for a todo list in JavaScript?
todoList.addEventListener('click', e => { if (e.target.matches('.delete-btn')) e.target.closest('li').remove(); if (e.target.matches('.toggle-btn')) e.target.closest('li').classList.toggle('done'); }). One listener handles delete and toggle for all items.

cart.addEventListener('click', e => { if (e.target.matches('.increase')) updateQty(e.target.dataset.id, 1); if (e.target.matches('.decrease')) updateQty(e.target.dataset.id, -1); if (e.target.matches('.remove')) removeItem(e.target.dataset.id); }).
table.addEventListener('click', e => { const row = e.target.closest('tr'); if (e.target.matches('.sort-btn')) sortTable(e.target.dataset.column); if (e.target.matches('.edit-btn')) editRow(row.dataset.id); }).
tabs.addEventListener('click', e => { if (e.target.matches('.tab')) switchTab(e.target.dataset.tab); }). One listener on the tab container handles all tab clicks. Check e.target.matches('.tab') and use dataset.tab to identify which tab.
