functional programming - What is Scala's yield? -


I understand the yield of ruby ​​and python what does scalla yield?

Use it (such as list-understanding and generator of Python), where you yield can also be used).

It is applied in combination with and writes a new element in the resulting sequence.

> Simple Examples (from)

  / ** Command Line Organisms Uppercase * / Object Main {ARF: Array [String]) {val res = for (a  

F # will have related expression

  [ For a args - & gt; A.toUpperCase] ​​ 

or

  Choose from an ARG a.toUpperCase  

in Linq.

Ruby has a different effect of yield .
