+Create a function named `getJSON` with two parameters:
+- `path`: a URL called by your function.
+- `params`: optional query parameters that will be appended to the `path`.
 
-- `path`, that will be the url called by your function
-- `params` _optional_, that will be the search parameters appended to your url
+`getJSON` must construct a valid url with the `path` and stringified `params`, and use `fetch` to fulfil the request.
 
-`getJSON` must construct a valid url with the `path` and stringified `params`
-and call `fetch` with it.
-If the response is not ok, your function must throw an error using
-the response status message.
