At Zap.sol init function you have the for loop pattern:
for (uint256 i = 0; i < array.length; i++) {
// do something with array[i]
}
In such for loops, the `array.length` is read on every iteration, instead of caching it once in a local variable and read it again using the local variable.
## Impact
Storage reads are much more expensive than reading local variables. Memory and calldata reads are a bit more expensive than reading local variables.
## Tool Used
Manual code review.
## Recommended Mitigation Steps
Read these values from storage / memory / calldata once, cache them in local variables and then read them again using the local variables. For example:
uint256 length = array.length;
for (uint256 i = 0; i < length; i++) {
// do something with array[i]
}
