Reading Time: 2 minutes As we already know that Dotty is the new Scala version and will obviously be more stronger and powerful then Scala 2.In Scala-2, pattern matching is only applicable to the objects and not on the types. But with the new Scala compiler i.e Dotty, it is possible to apply matching on Types also. For example, The Container is a type which gets reduce to further Continue Reading

Reading Time: 2 minutes The Scala language provides to ways to implement the collections. One is strict and other is non-strict or lazy. Whenever, the instance of a collections in scala(except for the Streams) is created, it creates the strict version of the collection which means memory is allocated at the same time. A simple example of strict collection is: val list = List(1,2,3,4,5,6,7,8,9,10) list: List[Int] = List(1, 2, Continue Reading
