## Get Json

|
### Instructions
|
||
|
|
|
||
|
|
In this exercise, we will focus on building complex async flows with promises.
|
||
|
|
|
||
|
|
Create a `getJSON` function that takes 2 parameters:
|
||
|
|
- `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 call `fetch` with it.
|
||
|
|
If the response is not ok, your function must throw an error using
|
||
|
|
the response status message.
|
||
|
|
|
||
|
|
The response body must then be read and parsed from json.
|
||
|
|
|
||
|
|
The parsed object contains one of those 2 properties:
|
||
|
|
- `"data"` the actual data to return
|
||
|
|
- `"error"` the error message to throw
|
||
|
|
|
||
|
|
|
||
|
|
