Selection: focusNode property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The Selection.focusNode read-only property returns the Node in which the selection ends. It can return null if selection never existed in the document (e.g., an iframe that was never clicked on, or the node belongs to another document tree).
A user may make a selection from left to right (in document order) or right to left (reverse of document order). The focus is where the user ended the selection. This can be visualized by holding the Shift key and pressing the arrow keys on your keyboard. The selection's focus moves, but the selection's anchor, the other end of the selection, does not move.
Value
A Node object or null.
