// Node.js program to demonstrate the
// fs.readlinkSync() method
// Import the filesystem module
const fs = require('fs');
// Create a symbolic link
fs.symlinkSync(__dirname + "\\example_file.txt",
"symlinkToFile", 'file');
console.log("\nSymlink created\n");
// Get the path of the symbolic link
symlinkPath = fs.readlinkSync("symlinkToFile");
console.log("Path of the symlink:", symlinkPath);
