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.
Here's an example:
countByView(campgrounds, "ocean"); //-> 3
countByView(campgrounds, "forest"); // -> 2
Dataset
As a reminder, the data looks like this. 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 },
