--description--

We will now use our knowledge of strings to build a "Mad Libs" style word game we're calling "Word Blanks". You will create an (optionally humorous) "Fill in the Blanks" style sentence.

In a "Mad Libs" game, you are provided sentences with some missing words, like nouns, verbs, adjectives and adverbs. You then fill in the missing pieces with words of your choice in a way that the completed sentence makes sense.

Consider this sentence - It was really ____, and we ____ ourselves ____. This sentence has three missing pieces- an adjective, a verb and an adverb, and we can add words of our choice to complete it. We can then assign the completed sentence to a variable as follows:

const sentence = "It was really " + "hot" + ", and we " + "laughed" + " ourselves " + "silly" + ".";

--instructions--

In this challenge, we provide you with a noun, a verb, an adjective and an adverb. You need to form a complete sentence using words of your choice, along with the words we provide.

You will need to use the string concatenation operator + to build a new string, using the provided variables: myNoun, myAdjective, myVerb, and myAdverb. You will then assign the formed string to the wordBlanks variable. You should not change the words assigned to the variables.

You will also need to account for spaces in your string, so that the final sentence has spaces between all the words. The result should be a complete sentence.

--hints--

wordBlanks should be a string.

assert(typeof wordBlanks === 'string');

You should not change the values assigned to myNoun, myVerb, myAdjective or myAdverb.

assert(
  myNoun === 'dog' &&
    myVerb === 'ran' &&
    myAdjective === 'big' &&
    myAdverb === 'quickly'
);

You should not directly use the values dog, ran, big, or quickly to create wordBlanks.

const newCode = removeAssignments(code);
assert(
  !/dog/.test(newCode) &&
    !/ran/.test(newCode) &&
    !/big/.test(newCode) &&
    !/quickly/.test(newCode)
);

wordBlanks should contain all of the words assigned to the variables myNoun, myVerb, myAdjective and myAdverb separated by non-word characters (and any additional words in your madlib).

assert(
  /\bdog\b/.test(wordBlanks) &&
    /\bbig\b/.test(wordBlanks) &&
    /\bran\b/.test(wordBlanks) &&
    /\bquickly\b/.test(wordBlanks)
);

const removeAssignments = str => str
  .replace(/myNoun\s*=\s*["']dog["']/g, '')
  .replace(/myAdjective\s*=\s*["']big["']/g, '')
  .replace(/myVerb\s*=\s*["']ran["']/g, '')
  .replace(/myAdverb\s*=\s*["']quickly["']/g, '');

--seed-contents--

const myNoun = "dog";
const myAdjective = "big";
const myVerb = "ran";
const myAdverb = "quickly";

// Only change code below this line
const wordBlanks = ""; // Change this line
// Only change code above this line

--solutions--

const myNoun = "dog";
const myAdjective = "big";
const myVerb = "ran";
const myAdverb = "quickly";

let wordBlanks = "Once there was a " + myNoun + " which was very " + myAdjective + ". ";
wordBlanks += "It " + myVerb + " " + myAdverb + " around the yard.";
