`Solidity Static Analysis` plugin performs static analysis on Solidity smart contracts once they are compiled. It helps to check security vulnerabilities and bad development practices. This plugin comes with `Solidity` environment of Remix IDE. It can also be activated individually from `Plugin Manager`.

- **For loop over dynamic array: Iterations depend on dynamic array's size**
Loops that do not have a fixed number of iterations, for example, loops that depend on storage values, have to be used carefully: Due to the block gas limit, transactions can only consume a certain amount of gas. The number of iterations in a loop can grow beyond the block gas limit which can cause the complete contract to be stalled at a certain point. Additionally, using unbounded loops incurs in a lot of avoidable gas costs. Carefully test how many items at maximum you can pass to such functions to make it successful.

- **Delete from dynamic array: 'delete' on an array leaves a gap**
Using `delete` on an array leaves a gap. The length of the array remains the same. If you want to remove the empty position you need to shift items manually and update the length property.
