This is a worst case O(N) operation, which is quite expensive as it grows at the same time as the size of your data.
One thing that we can do about this is inspired by caching. Caching is about storing the most-accessed elements in a "close" place, drastically reducing the complexity of retrieving elements from sequential data structures.
