 const fs = require("fs").promises;

const path = require("path");

async function findFiles(folderName) {
  const items = await fs.readdir(folderName, { withFileTypes: true });
  items.forEach((item) => {
    if (path.extname(item.name) === ".json") {
      console.log(`Found file: ${item.name} in folder: ${folderName}`);
    } else {
      findFiles(path.join(folderName, item.name));
    }
  });
}
findFiles("stores");

Found file: sales.json in folder: stores\203
Found file: sales.json in folder: stores\201\204
Found file: sales.json in folder: stores\201\204\202
