* fix: non-suggestion comments

* chore(learn): remove comments from codes

Removes the comments from the description and instruction code
blocks to ensure that all relevant information is translatable.

* fix: Apply suggestions from code review

--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--

Object.keys(bob).length should return 6.

assert.deepEqual(Object.keys(bob).length, 6);

bob instanceof Person should return true.

assert.deepEqual(bob instanceof Person, true);

bob.firstName should return undefined.

assert.deepEqual(bob.firstName, undefined);

bob.lastName should return undefined.

assert.deepEqual(bob.lastName, undefined);

bob.getFirstName() should return the string Bob.

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

bob.getLastName() should return the string Ross.

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

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

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

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

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

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

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

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

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

--seed--

--after-user-code--

if(bob){
  bob = new Person("Bob Ross");
}

--seed-contents--

var Person = function(firstAndLast) {
  // Only change code below this line
  // Complete the method below and implement the others similarly
  this.getFullName = function() {
    return "";
  };
  return firstAndLast;
};

var bob = new Person('Bob Ross');
bob.getFullName();

--solutions--

var Person = function(firstAndLast) {

  var firstName, lastName;

  function updateName(str) {
    firstName = str.split(" ")[0];
    lastName = str.split(" ")[1];
  }

  updateName(firstAndLast);

  this.getFirstName = function(){
    return firstName;
  };

  this.getLastName = function(){
    return lastName;
  };

  this.getFullName = function(){
    return firstName + " " + lastName;
  };

  this.setFirstName = function(str){
    firstName = str;
  };


  this.setLastName = function(str){
    lastName = str;
  };

  this.setFullName = function(str){
    updateName(str);
  };
};

var bob = new Person('Bob Ross');
bob.getFullName();
