How do you implement ellipsis in pagination?
If total <= 7, show all pages. If current is near start: [1, 2, 3, 4, 5, '...', total]. If near end: [1, '...', total-4, total-3, total-2, total-1, total]. If in middle: [1, '...', current-1, current, current+1, '...', total].

When the total number of pages is more than 7 (or your chosen threshold). Showing 100 page buttons is impractical. Ellipsis keeps the pagination compact by showing the first, last, current, and neighbor pages with '...' for gaps.
Check if the page number is '...': if (p === '...') return '<span class="ellipsis">...</span>'. Otherwise, render a button. The ellipsis is a span (not a button, not clickable), while page numbers are buttons.
The current page, its immediate neighbors (current - 1 and current + 1), the first page, and the last page. This gives context (where am I, where can I go) without showing every page. The gaps are filled with ellipsis.
