I am wondering if the attached image that represents how JSON data is returned from a stock market API is improperly formatted JSON data. Here is a link to the API call that the image pictorially represents: https://api.iextrading.com/1.0/stock/market/batch?symbols=A,AAPL&types=chart&range=1d
The API call essentiall returns market data for 1 day of both stock symbol A and AAPL (as an example). However, I thought JSON is typically [{}, {}, {}] or {[{}, {}]} format but this API batch request is {{[{}, {}]}}.
Would be much appreciated is someone could provide some insight.
