Below programs illustrates the use of fs.Dir.close() method in Node.js
Example 1:
Filename: GFG.js
Javascript
// Node program to demonstrate the // dir.close() methodconst fs = require('fs');// Initiating async functionasync function stop(path) { // Creating and initiating directory's // underlying resource handle const dir = await fs.promises.opendir(path); // Asynchronously closing the directory's // underlying resource handle const promise = dir.close(); // Display the result console.log(promise);}// Catching errorstop('./').catch(console.error); |
Run GFG.js file using the following command:
node GFG.js
Output:
Example 2:
Javascript
// Node program to demonstrate the // dir.close() APIconst fs = require('fs');// Initiating async functionasync function stop(path) { let dir = null; try { // Creating and initiating directory's // underlying resource handle dir = await fs.promises. opendir(new URL('file:///F:/java/')); } finally { if (dir) { // Display the result console.log("dir is closed successfully"); // Close the file if it is opened. await dir.close(); } }}// Catching errorstop('./').catch(console.error); |
Run GFG.js file using the following command:
node GFG.js
Output:
Note: The above program will not run on online JavaScript and script editor.
