• Mouse Movement Function: The React app defines a function named onMouseMoveCaptureHandler that logs a message when the mouse moves.
• User Greeting: The app displays a greeting “Hey Geek!” in an <h1> tag.
• Interactive Element: A paragraph encourages users to move their mouse on it, triggering the defined function (onMouseMoveCaptureHandler) when the mouse moves over the paragraph.

Syntax:

<element  onMouseMoveCapture={function}/>

The onMouseMoveCapture in React serves as an event handler activated when the mouse moves over an element. Unlike onMouseMove, it operates during the capture phase, contrasting with onMouseMove, which functions during the bubbling phase of an event.
