Ans:

Node.js provides an inbuilt component called FS (File System). The Node. js file system module enables us to interact with our computer's file system.

1. This problem occurs when a file does not exist; therefore, check to see if the file exists first.
2. The suitable approach is to use fs.openSync, it returns the file descriptor.
3. If the file does not exist, the w flag ensures that it is created, and if it does, it is overwritten with a new file, overriding its content.
4. If users don't need the file descriptor, users can close the file by wrapping the call in a fs.closeSync() call.

//check if file exist
if (!fs.existsSync('student.json')) {
    //create new file if not exist
    fs.closeSync(fs.openSync('student.json', 'w'));
}
