Why create an array each time it iterates a Set rather than just iterating the Set?

Why create an array each time it iterates a Set rather than just iterating the Set?
- willybrauner 6mo agoI create a new copy of the Set because the functions called during the loop might modify it by removing elements via cleanup functions. Without a copy, iterating directly on the Set could cause unpredictable behavior.
- willybrauner 6mo agoBut as the article points out, this is a naive implementation. It could be discussed and greatly improved.
