Line in question

         * Decodes a string of Base64-encoded data into bytes, and encodes those bytes
         * into a string using Latin-1 (ISO-8859-1).
         *
         * The `data` may be any JavaScript-value that can be coerced into a string.
         *
         * **This function is only provided for compatibility with legacy web platform APIs**
         * **and should never be used in new code, because they use strings to represent**
         * **binary data and predate the introduction of typed arrays in JavaScript.**
         * **For code running using Node.js APIs, converting between base64-encoded strings**
         * **and binary data should be performed using `Buffer.from(str, 'base64')` and`buf.toString('base64')`.**
         * @since v15.13.0, v14.17.0
         * @deprecated Use `Buffer.from(data, 'base64')` instead.
         * @param data The Base64-encoded input string.
