Scala: how to understand the flatMap method of Try?

Question

The flatMap method of the Success is implemented like this:

  def flatMap[U](f: T => Try[U]): Try[U] =
    try f(value)
    catch {
      case NonFatal(e) =&g         


        

Answer 1

You may consider Try[T] as similar to a collection of only one element (like Option[T]) .

When the "sequence of sequences" is "only one sequence", map and flatmap are almost similar. Only difference being the signature of the function.

No flattening is required in this case.
