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. Remember to use Read-Search-Ask if you get stuck. Try to pair program. Write your own code.

Challenge Seed

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

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

Solution

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();
