The difference between the two is that the Enumerator will raise a StopIteration exception if it doesn't complete the iteration before reaching the end. So if your block only requires 2 arguments, then each will use the array indices to build a two element tuple.īut when your block is more complex, the Ruby docs show you should use it's Enumerator counterpart and the each method. The array equivalent is the each method which will perform the iteration using indices if the block is only ever called with two arguments. The ruby documentation shows that the foreach is designed to iterate over a sequence element by element. Good question but I fear the answer is "No".
