How can you pick specific elements from an array in JavaScript and place them into a new array?

Looking to choose a single element from one array out of multiple elements in another array. Here is the structure of the array:

{
    "f": "Book2.csv",
    "v": 0,
    "vs": ["Year", "Month", "Customer_ID", "Collateral", "Exposure_amount"],
    "xs": ["Customer_type", "Region", "Collateral_type", "Collateral_value"],
    "y": 1,
    "x": 0,
    "ys": ["Customer_type", "Region", "Collateral_type", "Collateral_value"]
}

I am attempting to extract "Customer_type" from the "xs" array.

var custype = data["xs"][data["x"]];

An error has occurred:

SyntaxError: missing ; before statement

How can this issue be resolved?

Answer №1

The element "Customer_type" occupies the first slot in the data.xs array, so to retrieve it, you would use

data["xs"][0]

If you are attempting to access the data["x"]" property, which is also in the first position, you can simply do

data["xs"][ data["x"] ]

Answer №2

Give this a shot:

 let customerType = data["xs"][0];
