Cannot get a value from API-CodePudding

I have an issue with an API call from polygon.io. I am using their free API which gives me information on stock tickers.

I am using an API that provides me a response when called. From the response, I need to get response > data > results > "c" value, in this case, 1014.97

So far the best I could do is: console.log(response.data.results)

which gives:

  Array [
  Object {
    "T": "TSLA",
    "c": 1014.97,
    "h": 1090.5753,
    "l": 1000.21,
    "n": 1043576,
    "o": 1084.79,
    "t": 1638565200000,
    "v": 30773995,
    "vw": 1028.7486,
  },

Please tell me how I can get the "c" value?

Here is the full response data:

console.log(response)

This, in VS-Code>Terminal shows:

CodePudding user response：

Since "results" is an array with a dictionary inside you can reference the close value with response.data.results['c'].

CodePudding user response：

Results is an array of dictionnary Object. The dictionnary Object containing "c" value is the first elements of the array. So, you can get it like this

response.data.results[0].c
