--description--

Fill in the object constructor with the following methods below:

getFirstName()
getLastName()
getFullName()
setFirstName(first)
setLastName(last)
setFullName(firstAndLast)

Run the tests to see the expected output for each method. The methods that take an argument must accept only one argument and it has to be a string. These methods must be the only available means of interacting with the object.

--hints--

No properties should be added. Object.keys(bob).length should always return 6.

assert.strictEqual(
  Object.keys((function () {
    let bob = new Person('Bob Ross');
    bob.setFirstName('Haskell');
    bob.setLastName('Curry');
    bob.setFullName('John Smith');
    return bob;
  })()).length,
  6
 );

bob instanceof Person should return true.

assert.deepEqual(_test_bob instanceof Person, true);

bob.firstName should return undefined.

assert.deepEqual(_test_bob.firstName, undefined);

bob.lastName should return undefined.

assert.deepEqual(_test_bob.lastName, undefined);

bob.getFirstName() should return the string Bob.

assert.deepEqual(_test_bob.getFirstName(), 'Bob');

bob.getLastName() should return the string Ross.

assert.deepEqual(_test_bob.getLastName(), 'Ross');

bob.getFullName() should return the string Bob Ross.

assert.deepEqual(_test_bob.getFullName(), 'Bob Ross');

bob.getFullName() should return the string Haskell Ross after bob.setFirstName("Haskell").

assert.strictEqual(
  (function () {
    _test_bob.setFirstName('Haskell');
    return _test_bob.getFullName();
  })(),
  'Haskell Ross'
);

bob.getFullName() should return the string Haskell Curry after bob.setLastName("Curry").

assert.strictEqual(
  (function () {
    var _bob = new Person('Haskell Ross');
    _bob.setLastName('Curry');
    return _bob.getFullName();
  })(),
  'Haskell Curry'
);

bob.getFullName() should return the string Haskell Curry after bob.setFullName("Haskell Curry").

assert.strictEqual(
  (function () {
    _test_bob.setFullName('Haskell Curry');
    return _test_bob.getFullName();
  })(),
  'Haskell Curry'
);

bob.getFirstName() should return the string Haskell after bob.setFullName("Haskell Curry").

assert.strictEqual(
  (function () {
    _test_bob.setFullName('Haskell Curry');
    return _test_bob.getFirstName();
  })(),
  'Haskell'
);

bob.getLastName() should return the string Curry after bob.setFullName("Haskell Curry").

assert.strictEqual(
  (function () {
    _test_bob.setFullName('Haskell Curry');
    return _test_bob.getLastName();
  })(),
  'Curry'
);
