{ (parameters) ->return type in statements}

Example: function implementation:


Let names = ["Chris", "Alex", "Ewa", "Barry", "Daniella"] funcbackwards (S1: String, S2: string) -> bool {return S1> S2} var reversed = sort (names, backwards) println (reversed) // The sort sorting function. Backwards uses the closure function to implement the sorting rule: vaR reversed = sort (names, {(S1: String, S2: string)-> bool inreturn S1> S2}) println (reversed)
