+# --description--
+
+In this lab, you will build a function that returns the length of the longest word in the provided sentence.
+
+For example, in the sentence `"The quick brown fox jumped over the lazy dog"`, the longest word is `"jumped"`, which has a length of 6.
+
+**Objective:** Fulfill the user stories below and get all the tests to pass to complete the lab.
+
+**User Stories:**
+
+1. You should create a function named `findLongestWordLength` that takes a string as an argument.
+2. The function should return the length of the longest word in the string.
+
+# --hints--
+
+You should create a function named `findLongestWordLength`.
+
+```js
+assert.isFunction(findLongestWordLength);
+```
+
+`findLongestWordLength` should have a single parameter.
+
+```js
+assert.lengthOf(findLongestWordLength, 1);
+```
+
+`findLongestWordLength("The quick brown fox jumped over the lazy dog")` should return a number.
+
+```js
+assert.isNumber(
+  findLongestWordLength('The quick brown fox jumped over the lazy dog')
+);
+```
+
+`findLongestWordLength("The quick brown fox jumped over the lazy dog")` should return `6`.
+
+```js
+assert.strictEqual(
+  findLongestWordLength('The quick brown fox jumped over the lazy dog'),
+  6
+);
+```
+
+`findLongestWordLength("May the force be with you")` should return `5`.
+
+```js
+assert.strictEqual(findLongestWordLength('May the force be with you'), 5);
+```
+
+`findLongestWordLength("Google do a barrel roll")` should return `6`.
+
+```js
+assert.strictEqual(findLongestWordLength('Google do a barrel roll'), 6);
+```
+
+`findLongestWordLength("What is the average airspeed velocity of an unladen swallow")` should return `8`.
+
+```js
+assert.strictEqual(
+  findLongestWordLength(
+    'What is the average airspeed velocity of an unladen swallow'
+  ),
+  8
+);
+```
+
+`findLongestWordLength("What if we try a super-long word such as otorhinolaryngology")` should return `19`.
+
+```js
+assert.strictEqual(
+  findLongestWordLength(
+    'What if we try a super-long word such as otorhinolaryngology'
+  ),
+  19
+);
+```
+
+# --seed--
+
+## --seed-contents--
+
+```js
+
+```
+
+# --solutions--
+
+```js
+function findLongestWordLength(str) {
+  return str.split(' ').sort((a, b) => b.length - a.length)[0].length;
+}
+
+findLongestWordLength('The quick brown fox jumped over the lazy dog');
+```
