奇怪的JSON键

Question

{
  "Meta Data": {
    "1: Symbol": "MSFT",
    "2: Indicator": "Triple Exponential Moving Average (TEMA)",
    "3: Last Refreshed": "2017-06-26 16:00:00",
    "4: Interval": "15min",
    "5: Time Period": 10,
    "6: Series Type": "close",
    "7: Time Zone": "US/Eastern"
}
}

Let me first start off by saying that I just started learning JSON and AJAX, so this may sound like a stupid question. Recentely though, I found this JSON output text. But there a couple of problems I have with it. First of all, some keys have two words in them, without a _ . How can you then use them in javascript? I mean you cannot have a method with a space in it, right? And my second problem is related to the first problem, since there are also some keys that even start out like this 1: or 2: . What's up with that? So if anyone can show me how I can for example reach the "5: time period" key in javascript, that would be a huge help.

Answer 1

The keys in this case are just strings, so you would access them using strings. Assuming you've loaded this JSON into a val variable, you could use

val["Meta Data"]["1: Symbol"]
