Very cool snippet showing the use of a JS generator to walk a directory recursively. Yields the path of files found.

recursive-file-lister-generator.js

/**
* @param {string} rootPath
* @returns {Generator<string>}
*/
function* walk(rootPath) {
    for (const entry of fs.readdirSync(rootPath, { withFileTypes: true })) {
        const filePath = path.join(rootPath, entry.name);
        if (entry.isDirectory()) yield* walk(filePath);
        else yield filePath;
    }
}
