Review the following information on arrays, which will prove to be critical in understanding the logic error in this exercise. An is analogous to a list of items. In this example, our image slides in our slideshow are treated as items in an array. Every image in our array has an "index," a number that represents where that item is in the array. For example, the first image slide in our array has an index of the second image has an index of 1 , and so on. You can identify and "access" these items using their index number. There are a few approaches you can take to accessing items in an array. To give you some ideas, review the example below: var example = ["banana", "apple", "peach", "grapes"] ; // Our JavaScript array: a list of strings var first_element = example [0] // Retrieving the first item in the array, "banana" var last_element = example [example. length -1]; // Retrieving the last item in the array, "grapes" console. log (first_element); console. log ( last_element); // Will output "banana" and "grapes" Arrays are a common variable type in most programming languages and can be used in a many situations, such as our slideshow here.
