30It's easy enough. Now s is a stream with three elements: 10, 20, and 30; in order. We can use s. length () to view the stream length, and use s. item (I) to retrieve an element from the index. You can also call s. head () to obtain the first element of the stream. Let's perform the following operations:Copy codeThe Code is as follows:Var s = Stream. make (10, 20, 30 );Console. log (s. length (); // outputs 3Console. log (s. head (); // outputs 10Console. log (s. item (0); // exactly equivalen
