What is the purpose of the Sequelize transaction() method and when is it critical to use it?

Accepted Answer

The Sequelize transaction() method is used to wrap multiple database operations in an ACID transaction, ensuring all operations succeed or all are rolled back. This is critical for operations that must remain consistent, such as transferring funds between accounts.
