 * your rows JSON; consumers load it via `Fuse.parseIndex` at runtime to
 * skip the in-browser build cost).
 *
 * Workflow:
 *
 *   // Build time (Node)
 *   const { rows, indexJson } = await prebuildFuseIndex(urls, fuseOptions);
 *   writeFileSync('public/searchIndex.documents.json', JSON.stringify(rows));

 *   ]);
 *   const fuseIndex = Fuse.parseIndex(indexJson);
 *   const fuse = new Fuse(rows, fuseOptions, fuseIndex);
 *
 * Cuts in-browser first-paint Fuse build time from ~10s (at 2K rows) to
 * ~200ms parse. For corpora < 1K rows the difference is barely visible;
 * for corpora > 1K rows it's a meaningful UX improvement.

 * Added in 1.2.
