Transactions in CouchDB allow you to execute a sequence of operations on the database atomically, meaning that either all operations succeed or none of them do. This ensures consistency when multiple documents are being modified concurrently. To use transactions, wrap your operations inside a `function` block and define the `lang` parameter as 'javascript' or 'erlang'. If an error occurs during any operation within the transaction, the entire transaction will be rolled back.
