Module parse failed: Identifier directly after number when using retext-emoji

I don’t know how to fix this. I ony import emoji from ‘retext-emoji’ and some errors display below:

./node_modules/retext-emoji/index.js 25:17
Module parse failed: Identifier directly after number (25:17)
File was processed with these loaders:
 * ./node_modules/babel-loader/lib/index.js
You may need an additional loader to handle the result of these loaders.

| const own = {}.hasOwnProperty;
> const vs16 = 0xfe_0f;
| /** @type {Record<string, gemoji[number]>} */
