 ## View
 
 Analogous to `slice` in other languages, the view is a reference to a 
-specific segment of collections. You can use `data[start..end]` to create a 
+specific segment of collections. You can use `data[start:end]` to create a 
 view of array `data`, referencing elements from `start` to `end` (exclusive). 
 Both `start` and `end` indices can be omitted.
