I haven't used either library, but, here's my initial analysis (I've read quite a bit of SICP, but not the whole thing admittedly).
stream.js
is an implementation of a functional style data structure for a list. Many data structures in a functional language tend to be recursive, much like the Stream
structure. It is composed of a head element, and a Stream
for the tail (subsequent elements). Here, lazy evaluation can be achieved by allowing the tail to be a function (i.e. infinite sequences).
Now, to answer your question, all of the functions provided by linq.js
should be able to be defined with other common higher order functions like map, reduce, walk, fold, etc.
Sure, stream.js
does not implement the Any()
method from linq.js
, but you can just do that with reduce()
.
