Word Blanks

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

Problem Explanation:

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.

You will need to use string operators to build a new string, result, using the provided variables: myNoun, myAdjective, myVerb, and myAdverb.

You will also need to use additional strings, which will not change, and must be in between all of the provided words. The output should be a complete sentence.

We have provided a framework for testing your results with different words. The tests will run your function with several different inputs to make sure all of the provided words appear in the output, as well as your extra strings.

• Change the code below //Your Code here and up to //Change this line.
• Take note that you are editing the inside of the wordBlanks() function.
• You will have basically created a sentence with the provided string variables.

Hint: 1

+ can be used for concatenating strings.

Hint: 2

Just as you can chain strings by concatenating, you can assign them to an existing variable instead of a new one.

Hint: 3

+= will allow you to use an existing variable, a string type in this case. Remember to add your own non-letters in between each variable.

Basic Code Solution:

function wordBlanks(myNoun, myAdjective, myVerb, myAdverb) {
    var result = "";
    // Your code below this line
    result+= "My "+myAdjective+" "+myNoun+" "+myVerb+" very "+myAdverb+".";

    // Your code above this line
  return result;
}

// Change the words here to test your function
wordBlanks("dog", "big", "ran", "quickly");

Example Run

• Test wordBlanks("dog", "big", "ran", "quickly"); runs.
• Variable result is declared with an empty string "".
• result will be changed with a new string composed of the concatenated strings "dog", "big", "ran", "quickly" through the variables myNoun, myAdjective, myVerb, myAdverb respectively; the order is changed and whitespace added.
• result is returned.

Code Explanation:

• Use result to concatenate the given variables.
• Separate words with whitespace and appropriate words to form the full sentence.
