-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.
