--description--

In this lab, you will create two different stories using a sentence template. You will use variables to store different parts of the story and then output the stories to the console.

Objective: Fulfill the user stories below and get all the tests to pass to complete the lab.

User Stories:

  1. You should declare the following variables using let:

    • adjective
    • noun
    • verb
    • place
    • adjective2
    • noun2

  2. You should assign the above variables some string values of your choice.

  3. You should declare a firstStory variable.

  4. You should use the following story template to create the first story and assign it to the firstStory variable: "Once upon a time, there was a(n) [adjective] [noun] who loved to eat [noun2]. The [noun] lived in a [place] and had [adjective2] nostrils that blew fire when it was [verb].";

  5. You should output your first story to the console using the message "First story: [firstStory]".

  6. You should assign new values to your adjective, noun, verb, place, adjective2, and noun2 variables.

  7. You should declare a secondStory variable.

  8. Create another story using the same template and assign it to the secondStory variable.

  9. You should output your second story to the console using the message "Second story: [secondStory]".

--hints--

You should declare an adjective variable.

js
assert.isNotNull(adjective);

You should declare a noun variable.

js
assert.isNotNull(noun);

You should declare a verb variable.

js
assert.isNotNull(verb);

You should declare a place variable.

js
assert.isNotNull(place);

You should declare an adjective2 variable.

js
assert.isNotNull(adjective2);

You should declare a noun2 variable.

js
assert.isNotNull(noun2);

You should assign a string value to the adjective variable.

js
assert.isString(adjective);

You should assign a string value to the noun variable.

js
assert.isString(noun);

You should assign a string value to the verb variable.

js
assert.isString(verb);

You should assign a string value to the place variable.

js
assert.isString(place);

You should assign a string value to the adjective2 variable.

js
assert.isString(adjective2);

You should assign a string value to the noun2 variable.

js
assert.isString(noun2);

You should declare a firstStory variable.

js
assert.isNotNull(firstStory);

You should use the correct story format for the first story: "Once upon a time, there was a(n) [adjective] [noun] who loved to eat [noun2]. The [noun] lived in a [place] and had [adjective2] nostrils that blew fire when it was [verb].". Pay attention to spaces.

js
const _initialValues = {}
for (const name of ['adjective', 'noun', 'noun2', 'place', 'verb', 'adjective2']) {
    const match = code.match(new RegExp(String.raw`${name}\s*=\s*('|"|${'`'})(?<${name}>.*?)\1(?:,|;|\s|$)`, 'm'));
    _initialValues[name] = match ? match.groups[name] : null;
}

const expected = `Once upon a time, there was a(n) ${_initialValues['adjective']} ${_initialValues['noun']} who loved to eat ${_initialValues['noun2']}. The ${_initialValues['noun']} lived in a ${_initialValues['place']} and had ${_initialValues['adjective2']} nostrils that blew fire when it was ${_initialValues['verb']}.`;

assert.strictEqual(firstStory, expected);

You should assemble your first story using the variables you declared in the correct order.

js
assert.match(
  __helpers.removeJSComments(code),
  /firstStory\s*=\s*.*?adjective.*?noun.*?noun2.*?noun.*?place.*?adjective2.*?verb/
);

You should log your first story using the message "First story: [firstStory]".

js
const condition1 = /console\.log\(\s*["']First\s+story:\s+["']\s*\+\s*firstStory\s*\);?/gm.test(code);
const condition2 = /console\.log\(\s*`First\s+story:\s+\$\{firstStory\}`\s*\);?/gm.test(code);
assert.isTrue(condition1 || condition2);

You should declare a secondStory variable.

js
assert.isNotNull(secondStory);

You should reassign the adjective variable for the second story.

js
assert.lengthOf(__helpers.removeJSComments(code).match(/adjective\s*=\s*/g), 2);

You should reassign the noun variable for the second story.

js
assert.lengthOf(__helpers.removeJSComments(code).match(/noun\s*=\s*/g), 2);

You should reassign the verb variable for the second story.

js
assert.lengthOf(__helpers.removeJSComments(code).match(/verb\s*=\s*/g), 2);

You should reassign the place variable for the second story.

js
assert.lengthOf(__helpers.removeJSComments(code).match(/place\s*=\s*/g), 2);

You should reassign the adjective2 variable for the second story.

js
assert.lengthOf(__helpers.removeJSComments(code).match(/adjective2\s*=\s*/g), 2);

You should reassign the noun2 variable for the second story.

js
assert.lengthOf(__helpers.removeJSComments(code).match(/noun2\s*=\s*/g), 2);

You should use the correct story format for the second story: "Once upon a time, there was a(n) [adjective] [noun] who loved to eat [noun2]. The [noun] lived in a [place] and had [adjective2] nostrils that blew fire when it was [verb].". Pay attention to spaces.

js
const expected = `Once upon a time, there was a(n) ${adjective} ${noun} who loved to eat ${noun2}. The ${noun} lived in a ${place} and had ${adjective2} nostrils that blew fire when it was ${verb}.`;
assert.strictEqual(secondStory, expected);

You should assemble your second story using the variables you declared in the correct order.

js
assert.match(
  __helpers.removeJSComments(code),
  /secondStory\s*=\s*.*?adjective.*?noun.*?noun2.*?noun.*?place.*?adjective2.*?verb/
);

You should log your second story using the format "Second story: [secondStory]".

js
const condition1 = /console\.log\(\s*["']Second\s+story:\s+["']\s*\+\s*secondStory\s*\);?/gm.test(code);
const condition2 = /console\.log\(\s*`Second\s+story:\s+\$\{secondStory\}`\s*\);?/gm.test(code);
assert.isTrue(condition1 || condition2);

The firstStory should not be the same as the secondStory.

js
assert.notEqual(firstStory, secondStory);
