+1. Efficient stack oriented execution model
+2. Clear, easy to understand, and elegant syntax
+3. Rich of great commands useful for development
+4. Flexible and powerful data type system 
+
+## Example
+This is example code output FizzBuzz in the Stack Programing Language.
+```stack
+( (i) var
+    ((FizzBuzz) print )
+    ( 
+        ((Fizz) print )
+        (
+            ((Buzz) print )
+            (i print )
+            i 5 mod 0 equal if 
+        )
+        i 3 mod 0 equal if 
+    ) 
+    i 15 mod 0 equal if
+)
+(fizzbuzz) var
