What Is the Purpose of a ‘Revert’ Operation in a Smart Contract?

A 'revert' operation stops the execution of a smart contract, undoes any state changes that occurred during the transaction, and returns the remaining gas to the user's wallet. It is typically used when a condition is not met (e.g. insufficient balance, unauthorized call) to signal a failure and prevent unintended state updates.
