# --description--
|
||
|
|
|
||
|
|
We will now use our knowledge of strings to build a "[Mad Libs](https://en.wikipedia.org/wiki/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:
|
||
|
|
|
||
|
|
```js
|
||
|
|
var 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.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(typeof wordBlanks === 'string');
|
||
|
|
```
|
||
|
|
|
||
|
|
You should not change the values assigned to `myNoun`, `myVerb`, `myAdjective` or `myAdverb`.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(
|
||
|
|
myNoun === 'dog' &&
|
||
|
|
myVerb === 'ran' &&
|
||
|
|
myAdjective === 'big' &&
|
||
|
|
myAdverb === 'quickly'
|
||
|
|
);
|
||
|
|
```
|
||
|
|
|
||
|
|
You should not directly use the values "dog", "ran", "big", or "quickly" to create `wordBlanks`.
|
||
|
|
|
||
|
|
```js
|
||
|
|
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).
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(
|
||
|
|
/\bdog\b/.test(wordBlanks) &&
|
||
|
|
/\bbig\b/.test(wordBlanks) &&
|
||
|
|
/\bran\b/.test(wordBlanks) &&
|
||
|
|
/\bquickly\b/.test(wordBlanks)
|
||
|
|
);
|
||
|
|
```
|
||
|
|
|
||
|
|
