+Arrays may also be sliced when an index or index range is supplied:
+
+#### Slice by Index
+
+Slicing by an index will take a string from an array:
```ion
-# Slicing not yet implemented
+let array = [ 1 2 3 ]
echo @array[0]
-echo @array[0..3]
+echo @array[1]
+echo @array[2]
+
+echo [ 1 2 3 ][0]
+echo [ 1 2 3 ][1]
+echo [ 1 2 3 ][2]
+
+echo @[echo 1 2 3][0]
+echo @[echo 1 2 3][1]
+echo @[echo 1 2 3][2]
+```
+
+#### Slice by Range
-let i = 1
-echo @array[$i]
-echo @array[$i+1]
+Slicing by range will take a subsection of an array as a new array:
+
+```ion
+let array = [ 1 2 3 4 5 ]
+echo @array[0..1]
+echo @array[0...1]
+echo @array[..3]
+echo @array[3..]
+echo @array[..]
