+Create the function `crosswordSolver` that is able to solve an empty crossword puzzle.
 
 The function takes two arguments:
 1. an empty puzzle, passed as a string and
 2. a list of words to fill in the puzzle (no double words allowed)
 
-The function must return the puzzle filled with the input words.
+The function must print on the console a string representing the puzzle filled with the input words.
 
 The empty puzzle will be a string with the following rules:
 - each character will be either a number, a `.` or a `\n`;
 - a number represent the number of words starting from the specific position and a `.` represent a space that does not need to be filled. 
 
-If the puzzle or list of words provided as inputs does not guarantee a unique solution, or any other conditions stated above are not met, the function must return `'Error'`. 
+If the puzzle or list of words provided as inputs does not guarantee a unique solution, or any other conditions stated above are not met, the function must print `'Error'`. 
 
 ### Examples
 
 ```js
-console.log(crosswordSolver('2001\n0..0\n1000\n0..0', ['casa', 'alan', 'ciao', 'anta']))
-// output: 'casa\ni..l\nanta\no..n'
-```

+const emptyPuzzle = 
+`2001
+0..0
+1000
+0..0
+`
+const words = ['casa', 'alan', 'ciao', 'anta']
+
+console.log(crosswordSolver(emptyPuzzle, words))
+/* output:
+`
