1 00:00:01,060 --> 00:00:04,420 In this section, we are going to talk about closures and iterator. 2 00:00:05,140 --> 00:00:08,860 These two are often found inside a functional programming languages. 3 00:00:09,400 --> 00:00:15,640 Closures are a function like construct that you can store in a variable and iterator are a way of processing 4 00:00:15,640 --> 00:00:20,350 a series of elements, which is something we have seen and done before in this course. 5 00:00:20,560 --> 00:00:24,370 So let's dive right into what closures and iterator are.
