 We can create a `TypedArray` directly, without mentioning `ArrayBuffer`. But a view cannot exist without an underlying `ArrayBuffer`, so gets created automatically in all these cases except the first one (when provided).
 
-To access the `ArrayBuffer`, there are properties:
-- `arr.buffer` -- references the `ArrayBuffer`.
-- `arr.byteLength` -- the length of the `ArrayBuffer`.
+To access the underlying `ArrayBuffer`, there are following properties in `TypedArray`:
