--description--

Sometimes you will need to build a string, Mad Libs style. By using the concatenation operator (+), you can insert one or more variables into a string you're building.

Example:

var ourName = "freeCodeCamp";
var ourStr = "Hello, our name is " + ourName + ", how are you?";
// ourStr is now "Hello, our name is freeCodeCamp, how are you?"

--instructions--

Set myName to a string equal to your name and build myStr with myName between the strings "My name is " and " and I am well!"

--hints--

myName should be set to a string at least 3 characters long.

assert(typeof myName !== 'undefined' && myName.length > 2);

You should use two + operators to build myStr with myName inside it.

assert(code.match(/["']\s*\+\s*myName\s*\+\s*["']/g).length > 0);

--after-user-code--

(function(){
  var output = [];
  if(typeof myName === 'string') {
    output.push('myName = "' + myName + '"');
  } else {
    output.push('myName is not a string');
  }
  if(typeof myStr === 'string') {
    output.push('myStr = "' + myStr + '"');
  } else {
    output.push('myStr is not a string');
  }
  return output.join('\n');
})();

// Only change code below this line
var myName;
var myStr;

--solutions--

var myName = "Bob";
var myStr = "My name is " + myName + " and I am well!";
