    console.log(`This is ${flightname},${text}`);
  }
}

flightName.book('indigo', 'johnny');

you are calling your call funciton inccorect, call function is not supposed to work that way, as document stated: you should use it in this manner:

call()
call(thisArg)
call(thisArg, arg1)
call(thisArg, arg1, arg2)

so you need to change your code to:

book1.call(flightName,'johny', 'king');

Try this

const flightName ={

airline: 'luftansa',

itaCode: 'LH',

book: function(flightname,text)
{

console.log(`This is ${flightname},${text}`);
}

}

flightName.book('indigo','johnny');

let book1 = flightName.book;

book1.call(this, 'Johnny','King');
