FAQs
Is it possible to parallelize folding operations?
A: Indeed, folding may often be parallelized to increase performance, depending on how it is implemented and the nature of the operation.
What happens if there is nothing in the list?
A: The starting value is returned when folding an empty list without using the binary operator.
Which folding technique ought I to pick?
A: Depending on the particular needs of your calculation, performance concerns, evaluation order, and other criteria, you may choose between foldLeft, foldRight, and fold.
What are Folding Lists in Scala?
