What Is the Difference between Require() and Checking the Call Return Value?

The require() statement is used for internal checks within a function. If require() fails, it reverts the entire transaction and refunds the remaining gas.

Checking the call return value, however, handles the success or failure of an external contract interaction. If the external call fails, the transaction continues unless the developer explicitly checks the returned boolean and uses require() or revert() to stop the execution.
