Get the first object.

var obj = result[0];

Refer to the property of the object:

var prop = result[0].FirstName;

If property name comes dynamically, that is, from a variable, use square bracket notation.

var myVar = "FirstName";
var prop = result[0][myVar];

You have an array containing an object, so you have to retrieve the object by doing:

var myObj = result[0]

And then get the LastName property by:

var lastname = myObj.LastName
