--description--

Previously we have used the code

var myName = "your name";

"your name" is called a string literal. It is a string because it is a series of zero or more characters enclosed in single or double quotes.

--instructions--

Create two new string variables: myFirstName and myLastName and assign them the values of your first and last name, respectively.

--hints--

myFirstName should be a string with at least one character in it.

assert(
  (function () {
    if (
      typeof myFirstName !== 'undefined' &&
      typeof myFirstName === 'string' &&
      myFirstName.length > 0
    ) {
      return true;
    } else {
      return false;
    }
  })()
);

myLastName should be a string with at least one character in it.

assert(
  (function () {
    if (
      typeof myLastName !== 'undefined' &&
      typeof myLastName === 'string' &&
      myLastName.length > 0
    ) {
      return true;
    } else {
      return false;
    }
  })()
);

--after-user-code--

if(typeof myFirstName !== "undefined" && typeof myLastName !== "undefined"){(function(){return myFirstName + ', ' + myLastName;})();}

--solutions--

var myFirstName = "Alan";
var myLastName = "Turing";
