+####Description:
+
+The drawing shows 6 squares the sides of which have a length of 1, 1, 2, 3, 5, 8. It's easy to see that the sum of the perimeters of these squares is : 4 * (1 + 1 + 2 + 3 + 5 + 8) = 4 * 20 = 80
+
+Say that S(n) is the nth term of the above sum. So
+
+S(0) = 1, S(1) = 1, S(2) = 2, ... , S(5) = 8
+
+Could you give the sum S of the perimeters of all the squares in a rectangle when there are n + 1 squares disposed in the same manner as in the drawing:
+
+S = S(0) + S(1) + ... + S(n) ?

+
+###Hint:
+ See Fibonacci sequence and beware of rather big n :-)
+
+###Ref:
+ http://oeis.org/A000045
+
+The function perimeter has for parameter n where n + 1 is the number of squares (they are numbered from 0 to n) and returns the total perimeter of all the squares.
+
+	JS: Due to a misspelling in the reference solution for random tests, 
+	have an outer auxiliary function that calculates Fibonacci numbers, 
+	name this outer function fib. 
+	(More than 500 CW passed the kata so it is now impossible to change the random tests).
+
+####Example:
+
+```js
+perimeter(5) --> 80
+
+perimeter(7) --> 216
+
+```
+
