+//Answer: I predict that there will be a Reference Error, because str get's re-declared with let
+//inside the function even though it already is declared as it is the parameter. Perhaps it would
+// be solved by removing the "let".
 
 // call the function capitalise with a string input
 // interpret the error message and figure out why an error is occurring

 // =============> write your explanation here
