G-01: SIMILAR MAPPINGS CAN BE COMBINED INTO SINGLE MAPPING WITH STRUCT

This saves gas because this fields are accessed together in functions, if the mappings are combined the keccak256 hash will be calculated only once

-BasketHandler

G-02: var1 = var1 ± var2 is more gas efficient than var1±= var2

G-03: Declare Variables outside the loops

Declare the variable outside the loop once and reuse it inside the loop this way gas is not wasted to declare variable multiple times

G-04: Where overflow is impossible var1++ should be wraped in unchecked{} block

It saves gas because it compiler is not checking for overflows/underflows. This is more gas efficient but it makes code harder to read.

G-05: Put less gas consuming requires first

In this case if a transaction is reverted on first require less gas will be used.

G-06: Private functions which are used only once can be inlined

Calling private functions costs additional gas this way it will be saved. This might also make it a little bit harder to read the code.

G-07: Use bytes32 instead of string for strings smaller than 32 bytes

EVM workes with bytes32 more efficently than with strings and bytes.

-Deployer

G-08: Use calldata in cases where parameter variable is not modified

Accessing parameters from calldata are more gas efficient
