All the changes done in sub calls are also rolled back. If a contract A tries to do a token transfer in contract B but contract B reverts, all the changes done by contract A will also be rolled back. This is fine for some cases but sometimes there might be a need to ignore or handle this revert in the smart contract itself. The talk will demonstrate how reverts and other exceptions can be caught in Solidity.
