// Node.js program to demonstrate the

const fs = require('fs');
  
// Initiating asyn function
async function stop(path) {
  
    // Creating and initiating dir's 
    // underlying resource handle
    const dir = await 
        fs.promises.opendir(path);
  
    // Synchronously reading the dir's
    // underlying resource handle
    // using readSync() mehtod
    for (var i = 0; i <= 6; i++) {
  
        // Checking if the particular
        // dirent is SymbolicLink or 
        // not by using name() method
        const value = (dir.readSync()).name;
  
        // Display the result
        console.log(value);
    }
}
  
// Catching error
stop('./').catch(console.error);

abcd.cer
Dirent { name: 'certfile.cer', [Symbol(type)]: 1 }
cert.cer
Dirent { name: 'example.com_index.html', [Symbol(type)]: 1 }
