+
+## Description
+
+A stream of data is received and needs to be reversed.
+
+Each segment is 8 bits long, meaning the order of these segments needs to be reversed, for example:
+
+```
+11111111  00000000  00001111  10101010
+ (byte1)   (byte2)   (byte3)   (byte4)
+```
+
+should become:
+
+```
+10101010  00001111  00000000  11111111
+ (byte4)   (byte3)   (byte2)   (byte1)
+```
+
+The total number of bits will always be a multiple of 8.
+
+The data is given in an array as such:
+
+```
+[1,1,1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,1,0,1,0,1,0,1,0]
+```
+
+## Solution
+
+```javascript
+const dataReverse = data => {
+  if (data.length === 0) return []
+
+  return data
+    .join('')
+    .match(/\d{8}/g)
+    .reverse()
+    .join('')
+    .split('')
+    .map(character => Number(character))
+}
+```
