-### Level 2: Array of Strings
-
-Write code to calculate the average *length* of the strings inside of the following array:
-
-```javascript
-var words = [
-	"seat",
-	"correspond",
-	"linen",
-	"motif",
-	"hole",
-	"smell",
-	"smart",
-	"chaos",
-	"fuel",
-	"palace"
-];
-```
-
-**Starter Code**
-
-```javascript
-function averageWordLength(array){
-  // Your code here
-}
-
-var averageLength = averageNumbers(words);
-console.log(averageLength);
-// 5.3
-```
-
-## Unique Arrays
-
-Take the following array, remove the duplicates, and return a new array. You're more than likely going to want to check out the [`indexOf`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/indexOf) function.
-
-Do this in the form of a function.
-
-**Starter Code**
-
-```javascript
-function uniquifyArray(array){
-  // Your code here
-}
-
-var words = [
-  "crab",
-  "poison",
-  "contagious",
-  "simple",
-  "bring",
-  "sharp",
-  "playground",
-  "poison",
-  "communion",
-  "simple",
-  "bring"
-];
-
-var uniqued = uniquifyArray(words);
-console.log(uniqued);
-// ["crab", "poison", "contagious", "simple", "bring", "sharp", "playground", "communion"]
-```
-
-## Finding Elements
-
-Let's create a simple array search.
-
-Write a function that will take in an array of words as one argument, and a word to search for as the other. Return `true` if it exists, otherwise return `false`. **Don't** use `indexOf` for this one. :)
-
-**Starter Code**
-
-```javascript
-var words = [
-  "machine",
-  "subset",
-  "trouble",
-  "starting",
-  "matter",
-  "eating",
-  "truth",
-  "disobedience"
-];
-
-var hasMatter = doesWordExist(words, "matter");
-console.log(hasMatter);
-// true
-
-var hasDog = doesWordExist(words, "dog");
-console.log(hasDog);
-// false
-```
-
-## Counting Repetion
-
-Write a function that will take in an array of words as one argument, and a word to search for as the other. The function will return the number of times that word appears in the array.
-
-**Starter Code**
-
-```javascript
-var words = [
-  "machine",
-  "matter",
-  "subset",
-  "trouble",
-  "starting",
-  "matter",
-  "eating",
-  "matter",
-  "truth",
-  "disobedience"
-  "matter"
-];
-
-var howManyMatter = howManyTimes(words, "matter");
-console.log(howManyMatter);
-// 4
-
-var howManyDog = howManyTimes(words, "dog");
-console.log(howManyDog);
-// 0
-```

-## Bonus Quest
-
-In the 20×20 grid below; What is the greatest product of four adjacent numbers in the same direction (up, down, left, right)?
-
-```javascript
-var matrix = [
