Reduce Syntax Clojure

Hi! Here I shows you the Reduce Function Syntax in Clojure Programming Language.

And what I intend to Highlight here is simply the fact of an Initial Value to Set optionally.

Like map, reduce takes a Function and a Sequence and calls the Function for each Item in the Sequence.

Unlike map, reduce can take an Initial Value, and instead of acting on the Elements of the Set, produce a Final Result.

Each time reduce calls your Function, it Updates the Current Result with the Return Value from that call.

When reduce runs out of Elements, it returns the Last Result.

   Clojure Programming Reduce Syntax
   The General Form is:

   (reduce [Function] [Initial Value] [Set to Reduce])

   The “Initial Value” is Optional, but it’s worth also in case you want to Set the Data Type of the Result!
   So for Instance to convert a List of Arrays into a Set:

   (reduce into #{} '([] [10 18] [8 18] [10 12] [0 -6] [2 6]))
   => #{10 18 8 12 0 -6 2 6}
