I have an object with key value pairs inside an array:

var data = [

  {

  errorCode:100,

  message:{},

  name:InternetGatewayDevice.LANDevice.1.Hosts.HostNumberOfEntries,

  value:2

  }

];

I want to get the value of value key in the object. ie, the output should be 2.

I tried this:

console.log(data[value]);

console.log(data.value);

Both logging undefined. I saw similar questions in SO itself. But, I couldn't figure out a solution for my problem.

You are trying to get the value from the first element of the array. ie, data[0]. This will work:

console.log(data[0].value);

If you have multiple elements in the array, use JavaScript map function or some other function like forEach to iterate through the arrays.

data.map(x => console.log(x.value));



data.forEach(x => console.log(x.value));
