What is the difference between `require` and `if` statements when handling errors in Solidity?

While both `require` and `if` statements can be used to check conditions, `require` is specifically designed for error handling. It automatically reverts the transaction if the condition is false, preventing further execution. `if` statements, on the other hand, allow you to handle the error manually, potentially continuing execution with a default value or logging an error, but without halting the transaction.
