--description--

Just as we can build a string over multiple lines out of string literals, we can also append variables to a string using the plus equals (+=) operator.

Example:

var anAdjective = "awesome!";
var ourStr = "freeCodeCamp is ";
ourStr += anAdjective;

ourStr would have the value freeCodeCamp is awesome!.

--instructions--

Set someAdjective to a string of at least 3 characters and append it to myStr using the += operator.

--hints--

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

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

You should append someAdjective to myStr using the += operator.

assert(code.match(/myStr\s*\+=\s*someAdjective\s*/).length > 0);

--seed--

--after-user-code--

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

--seed-contents--

// Change code below this line

var someAdjective;
var myStr = "Learning to code is ";

--solutions--

var someAdjective = "neat";
var myStr = "Learning to code is ";
myStr += someAdjective;
