The finally Block

Code that always runs

The finally block runs whether or not an error occurred. Use it for cleanup tasks like closing connections or releasing resources.

try {
  openFile();
  processFile();
} catch (error) {
  logError(error);
} finally {
  closeFile(); // Always runs
}

Finally runs even if catch throws another error.
