How can I access JSON key with spaces

Below is the json data I am going to parse.

{
    "Global Quote": {
        "01. symbol": "AAPL",
        "02. open": "125.5700",
        "03. high": "125.8000",
        "04. low": "124.5500",
        "05. price": "124.6100",
        "06. volume": "71311109",
        "07. latest trading day": "2021-05-28",
        "08. previous close": "125.2800",
        "09. change": "-0.6700",
        "10. change percent": "-0.5348%"
    }
}

Normally, we can access the data using dot notation. However, given that there are spaces inside the key, we have to use squared bracket instead of dot notation. When I use 

console.log(stock)

after parsing the data and assign it to a variable called "stock", it returns all the data the same as above.

However, when I tried to access data using:

console.log(stock['01. symbol'])

it returns undefined.

Any idea or suggestion?

Hi! You are definitely thinking correctly, however, try stock["Global Quote"]["01. symbol"] as "01. symbol" is a nested property of the "Global Quote" object. :)

Yeap, I have figured it out. It was completely ignored by me
