Lesson 7 even cheaperWithdraw()

[shazKombatChain]

Hi community,

I'd like to add my version of the cheaperWithdraw function in the FundMe contract for lesson 7, this version saved even more gas but I would like to know your thoughts please:

   function cheaperWithdraw() public payable onlyOwner {
        address[] memory funders = s_funders;
        uint256 len = funders.length;
        for (uint256 funderIndex = 0; funderIndex < len; ) {
            address funder = funders[funderIndex];
            s_addressToAmountFunded[funder] = 0;
            unchecked {
                ++funderIndex;
            }
        }
        s_funders = new address[](0);
        (bool callSuccess, ) = payable(i_owner).call{
            value: address(this).balance
        }("");
        require(callSuccess, "Call failed");
    }

Very cool!
The unchecked keyword would 100% save a ton of gas, great work!
