    MDN Reference

    focusOffset: number

    The Selection.focusOffset read-only property returns the number of characters that the selection's focus is offset within the In the case of Selection.focusNode being another type of node, Selection.focusOffset returns the number of Node.childNodes the selection's focus is offset within the Selection.focusNode.
