    This is an experimental technology
    Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.

    The FocusEvent interface represents focus-related events like focus, blur, focusin, or focusout.

    Is an EventTarget representing a secondary target for this event. As in some cases (like when tabbing in or out a page), this property may be set to null for security reasons.
