+Remove the first element from an array but don't return it.
+
+```sig
+[""]._shiftStatement()
 ```
 
 The first element in the array is removed, so the array becomes smaller by one element.
@@ -13,29 +18,39 @@ If you have an array with 4 numbers, like 1, 2, 3, and 4, you remove the first n
 by _shifting_ it from the front. To shift the number from the array in blocks, do this:
 
 ```block
-let thoseNumbers = [1, 2, 3, 4];
-let firstNumber = thoseNumbers.shift();
+let thoseNumbers = [1, 2, 3, 4]
+let firstNumber = thoseNumbers.shift()
 ```
 
 ## Returns
 
 * the first element in the array.
 
+### ~reminder
+
+#### **shift** statement
+
+The ``||arrays:shift||`` **statement** only removes the first element from the array. It doesn't return it.
+
+```block
+["a", "b", "c"]._shiftStatement()
+```
+
+### ~
 ## Example
 
 Find out how many odd numbers there are as you remove all the numbers from a list.
 
 ```blocks
-let odds = 0;
-let ints = [45, 78, 98, 3, 5, 6, 12, 643, 0, 34, 4];
+let odds = 0
+let ints = [45, 78, 98, 3, 5, 6, 12, 643, 0, 34, 4]
 while (ints.length > 0) {
     if ((ints.shift() % 2) > 0) {
-        odds++;
+        odds++
     }
 }
 ```
