do we need a type here?

const pages: { url: string; title: string }[] = [];
function collect(node: Node) {
if (node.type === 'page') {
pages.push({ url: node.url, title: node.name?.toString() ?? '' });
} else if (node.type === 'folder') {
for (const child of node.children) collect(child);
}
}
for (const child of tree.children) collect(child);

const idx = pages.findIndex(p => p.url === pathname);
return {
prev: idx > 0 ? pages[idx - 1] : null,
next: idx >= 0 && idx < pages.length - 1 ? pages[idx + 1] : null,
};
}
