Gas Saving Techniques

This repository is mainly to test any gas saving technique we see or here about to know how much gas we really save to know whether it is effective.

for.sol - contains gas optimization techniques for for loop

require.sol - contains gas optimization techniques for handling reverts i.e require & custom reverts

return.sol - checks how much gas spent with the way we return valies in function calls

variables.sol - checks how much gas the various initialization of variables coding styles cost

if.sol - contains the best gas optimizing way to write multiple conditions in an if 

swap.sol - checks how much gas you will save when using two different styles in swapping variables


bitwise.sol - contains bitwise gas optimizations for common arithmetic operations like /2 or *4

bitwiseAccessControl.sol - is a style of access control using bitwise operators i saw and i think its cool
