Avoid Unnecessary Code Assignments

Description​

In Solidity, it is important to optimize gas usage in your contracts to keep them efficient and cost-effective. One common way to optimize gas usage is to avoid unnecessary code assignments. These are assignments that are performed when they are not needed and can waste valuable gas.

Example Code​

function test(uint256 x) external{
    Pool storage pool = Pools[x];
    uint256 someValue = (x.val1 * x.val2 / x.val3) - x.val4;
    if (someValue == 0){
        x.val4 = x.val1 * x.val2 / x.val3;
    }
}

Recommendation​

To optimize gas usage in Solidity contracts, it is important to avoid unnecessary code assignments. These are assignments that are performed when they are not needed and can waste valuable gas. Always review your code and remove any unnecessary assignments that can be avoided.
