Convert from json to array with knockout js

Question

I have json file 'stars.json':

   {"person":
 [
      {
        "name": "a"
      },
      {
        "name": "b"
      },
      {
        "name": "c"
      },
      {
        "name": "d"
      }
    ]
}

then I would like to send data to kendo element:

 $('#grid').kendoDropDownList({
     autoWidth: false,
        filter: "startswith",
        value: self.valore,
        optionLabel: "Select value...",
        dataSource: {

        }
 });

What should I do in the datasource to convert json to simple array? I would like to get something like this:

data=['a','b','c','d'];

You can use simply array function to get the results what you required

Suppose

var data = {"person":
 [
      {
        "name": "a"
      },
      {
        "name": "b"
      },
      {
        "name": "c"
      },
      {
        "name": "d"
      }
    ]
}

then use the array map function like this

var newData = data.person.map(function(obj){
    return obj.name
});
console.log(newData)

Considering there's a variable person with value:

{"person":[{"name":"a"},{"name":"b"},{"name":"c"},{"name":"d"}]}

you can simply do:

person.person.map((o)=> o.name)
