    Hi Vikram.. for the "Simple Marketplace" smart contract in the pdf.. I see there were two events declared towards the beginning of the contract.. but they were never used as the corresponding emit statements are missing from the program.
    From what I understood in the last lecture.. is that events are only used if you need to project something in the front-end, else they can be skipped, right?

    Everything looks good. Just one improvement which you do, use require function in Withdraw function instead of if & revert function.
