2 lines

3. Use existsSync() function to check if the file or directory exists:

index.tsx
const fileExists = fs.existsSync('/path/to/file');
const directoryExists = fs.existsSync('/path/to/directory');

if (fileExists) {
  console.log('File exists');
} else {
  console.log('File does not exist');
}

if (directoryExists) {
  console.log('Directory exists');
} else {
  console.log('Directory does not exist');
}

Note: existsSync() function is synchronous, which means it blocks the execution of the code until the file or directory existence has been checked. Therefore, it's recommended to use it for small operations on the file system. For large operations, you should use asynchronous functions.
