I was wondering which was the appropriate way to reset an array to initial state, and so delete all the elements that it contains.

I found the following ways:

  1. delete paidPlayers;
  2. paidPlayers.length = 0
  3. array = new type[](0)

I understand that those are equivalent from a result point of view, however I suppose there are differences about gas usage
