check given path is valid or not in nodejs

const fs = require('fs'); const path = '/path/to/your/file';

fs.access(path, fs.constants.F_OK, (err) => { if (err) { console.error('Path does not exist'); } else { console.log('Path exists'); } });

Explanation: 1. Import the file system module using require('fs') and assign it to the variable fs. 2. Define the path to the file or directory you want to check. 3. Use fs.access to check if the given path exists or not. The method takes the path, a constant that represents the mode of the file system access, and a callback function. 4. Within the callback function, check if an error occurred. If there is no error, the path exists; otherwise, it does not.
