O WEB PREVIEW RUN TESTS SUBMIT Instructions X IDE Help X Your Notes X Web Preview X ly Campground reservations, part 5: Count campsites by type of view Keep it up! You're doing great. How many campsites are there with each kind of view? We need to know how many campsites we have with each kind of view, regardless of whether they are currently reserved or not. Can you help us? Write a function called countByView that takes two arguments: • An array of campsites A string for the type, like 'ocean' or 'forest' It should return the total number of campsites with the view matching the input string, regardless of whether it is currently reserved or not.

It's an array with a bunch of campsite objects in it. Here is a small subset of the data to give you an idea: let campgrounds { number: 1, view: "ocean", partySize: 8, isReserved: false }, { number: 5, view: "ocean", partySize: 4, isReserved: false }, { number: 12, view: "ocean", partySize: 4, isReserved: true }, { number: 18, view: "forest", partySize: 4, isReserved: false }, { number: 23, view: "forest", partySize: 4, isReserved: true }, [ ];
