Handling Errors with try-catch-finally

What critical pattern is demonstrated here?

let transaction;
try {
  transaction = await db.begin();
  await performOperations();
  await transaction.commit();
} catch (error) {
  if (transaction) {
    await transaction.rollback();
  }
  throw error;
}

Basic error handling
Transaction management
