[G-1]- .LENGTH SHOULD NOT BE LOOKED UP IN EVERY LOOP OF A FOR-LOOP :

The array length used inside a loop for incrementing i must not be looked up in every iteration

line 167 : for (uint256 _i; _i < _terminalsOf[_projectId].length; _i++)

[G-2]- += COSTS MORE GAS THAN = + FOR STATE VARIABLES :

File: juice-contracts-v2-code4rena/contracts/JBTokenStore.sol

line 409 : unclaimedBalanceOf[_holder][_projectId] = unclaimedBalanceOf[_holder][_projectId] - _amount;
line 412 : unclaimedTotalSupplyOf[_projectId] = unclaimedTotalSupplyOf[_projectId] - _amount;
line 451 : unclaimedBalanceOf[_recipient][_projectId] = unclaimedBalanceOf[_recipient][_projectId] + _amount;

[G-3]- READING MEMORY VARIABLE INSTEAD OF STATE VARIABLE INSIDE A FOR LOOP :

File: juice-contracts-v2-code4rena/contracts/JBDirectory.sol

line 168 : if (_terminalsOf[_projectId][_i] == _terminal) return true;

[G-4]- USE OF ++i COST LESS GAS THAN i++ IN FOR LOOPS :

File: juice-contracts-v2-code4rena/contracts/JBDirectory.sol

line 167 : for (uint256 _i; _i < _terminalsOf[_projectId].length; _i++)

File: juice-contracts-v2-code4rena/contracts/JBOperatorStore.sol

line 85 : for (uint256 _i = 0; _i < _permissionIndexes.length; _i++);
