+# --description--
+
+In this lab, you will build a function that returns an array consisting of the largest number from each provided sub-array.
+
+Remember, you can iterate through an array with a simple `for` loop, and access each member with array syntax `arr[i]`.
+
+**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 `largestOfAll` that takes an array of arrays as an argument.
+2. The function should return an array containing the largest number from each sub-array.
+
+# --hints--
+
+You should create a function named `largestOfAll`.
+
+```js
+assert.isFunction(largestOfAll);
+```
+
+`largestOfAll` should take a single parameter.
+
+```js
+assert.lengthOf(largestOfAll, 1);
+```
+
+`largestOfAll([[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]])` should return an array.
+
+```js
+assert.isArray(
+  largestOfAll([
+    [4, 5, 1, 3],
+    [13, 27, 18, 26],
+    [32, 35, 37, 39],
+    [1000, 1001, 857, 1]
+  ])
+);
+```
+
+`largestOfAll([[13, 27, 18, 26], [4, 5, 1, 3], [32, 35, 37, 39], [1000, 1001, 857, 1]])` should return `[27, 5, 39, 1001]`.
+
+```js
+assert.deepEqual(
+  largestOfAll([
+    [13, 27, 18, 26],
+    [4, 5, 1, 3],
+    [32, 35, 37, 39],
+    [1000, 1001, 857, 1]
+  ]),
+  [27, 5, 39, 1001]
+);
+```
+
+`largestOfAll([[4, 9, 1, 3], [13, 35, 18, 26], [32, 35, 97, 39], [1000000, 1001, 857, 1]])` should return `[9, 35, 97, 1000000]`.
+
+```js
+assert.deepEqual(
+  largestOfAll([
+    [4, 9, 1, 3],
+    [13, 35, 18, 26],
+    [32, 35, 97, 39],
+    [1000000, 1001, 857, 1]
+  ]),
+  [9, 35, 97, 1000000]
+);
+```
+
+`largestOfAll([[17, 23, 25, 12], [25, 7, 34, 48], [4, -10, 18, 21], [-72, -3, -17, -10]])` should return `[25, 48, 21, -3]`.
+
+```js
+assert.deepEqual(
+  largestOfAll([
+    [17, 23, 25, 12],
+    [25, 7, 34, 48],

+    [-72, -3, -17, -10]
