What is guard in Scala’s for-comprehension construct?



What is guard in Scala’s for-comprehension construct?..

Answer / Loma Patwa

In Scala, a 'guard' is a condition that can be used within a for-comprehension construct to filter the elements of an iterator or collection. The syntax for using a guard is: GuardedFor((expr) if (condition) yield result). It returns only those elements for which the condition evaluates to true.
