Later you can call getCount() on the Consumer implementation to get the count. To do so, I wrapped the variable names in ${} - this is also known as string interpolation which allows you to introduce any variables without having to concatenate them like so: Another thing that template literals allow you to do is to use single quotes, double quotes, and apostrophes inside them without the need to escape them: String literals also allow you to create multiline strings, which you will learn how to do in the following section. We also have thousands of freeCodeCamp study groups around the world. It must take at least one parameter which represents the elements of an array: That's all we need to do for looping through the array: Alternatively, you can use the ES6 arrow function representation for simplifying the code: Alright now let's continue with the optional parameters. break doesn't work here. The question b) is answered already by other posters; on the other hand, the general question a) has a quite different answer: use a (possibly multi-line) lambda expression or pass a reference to multi-line method.
