尝试使用 JSON - 我做错了什么？ [等候接听]

Question

I am using a XMLHttpRequest to get a file, let's say someData.json which holds the following data:

{
    "language" : "english",
    "somethingElse" : "Hello world!",
}

When my callback function from the XMLHttpRequest is triggered the data is supplied as argJSONData . Now I am trying to work with my data, for example

function processJSONData(argJSONData)
{
    var myLanguage = argJSONData.language;
}

In this case, myLanguage is undefined although logging argJSONData shows up correctly, so I tried parsing the data into the JSON format like this

JSON.Parse(argJSONData);

which gives me this error message in my web console

TypeError: JSON.Parse is not a function

so I tried converting it into an array using

Array.from(argJSONData);

which made a huge array where each character is a hole entry, looking something like this

    0: "{"
​    1: "\r"
​​    2: "\n"
​​    3: " "
​​    4: " "
​​    5: " "
​​    6: " "
​    7: "\""
​    8: "l"
​​    9: "a"
   10: "n"

(this is not the end, but I think you get the idea)

Any ideas how I can make it work? I also tried replacing " with ' in my JSON file and much more, nothing works.

I am grateful for any help/feedback. Thank you.

Try using

JSON.parse(argJSONData);

might just be capitalization issue
