JavaScript
let person = {
    firstName: "John",
    lastName : "Doe",
    id     : 5566,
    fullName : function() {
      return this.firstName + " " + this.lastName;
    }
  }
  console.log(person.fullName()) //prints John Doe


When I am using arrow function here then I am getting undefined undefined as my output. Could anyone please let me know why this is happening. Below is my code with arrow function.

JavaScript
let person = {
    firstName: "John",
    lastName : "Doe",
    id     : 5566,
    fullName : () => {
      return this.firstName + " " + this.lastName;
    }
  }
  console.log(person.fullName()) //prints undefined undefined
