ES6 syntax.

JSON.parse(data).map((item) => { item.id , item.key })

ES5

JSON.parse(data).map(function(item){ return {item.id , item.key }})

Loop through it like this:

var jsonData = JSON.parse(data);
for(var myobject in jsonData){
     console.log("Id =" + myobject.id);
     console.log("key = " + myobject.key);
}

or like this:

var jsonData = JSON.parse(data);
for(i = 0; i < jsonData.length; i++){
     console.log("Id =" + jsonData[i].id);
     console.log("key = " + jsonData[i].key);
}

use map() function it will return te id and the key

var id = data.map(function(par){
    return  "id id :" +par.id+" key is: "+ par.key;
});

working see jsfiddle

Or you can is just a loop to access each key and id 

for(i = 0; i < data.length; i++){
   console.log("Id is :" + data[i].id+"key is : " + data[i].key);
}

var val1 = arr[0].id;
var k1 = arr[0].key;
var val2 = arr[1].id;
var k2 = arr[1].key;

To get the array lenght use arr.length
