React onMouseDownCapture is an event handler that gets triggered whenever we press the mouse button. like onMouseDown, but the difference is that onMouseDownCapture acts in the capture phase whereas onMouseDown acts in the bubbling phase i.e. phases of an event.
Prerequisites:
Syntax:
<element onMouseDownCapture={function}/>
Steps to Create the React Application:
Step 1: Create a react project folder
npm create-react-app project
Step 2: After creating your project folder(i.e. project), move to it by using the following command.

Project Structure:
The updated dependencies in package.json file will look like:
"dependencies": {
"react": "^18.2.0",
"react-dom": "^18.2.0",
"react-scripts": "5.0.1",
"web-vitals": "^2.1.4",

Example: In this example, we are adding a text within the <p> tag i.e. “Click Me!”, when the user will click on this element the onMouseDownCapture event will call onMouseDownCaptureHandler, a function that will show a text “onMouseDownCapture Event!” whenever we press the mouse button over the element.
function App() {
const onMouseDownCaptureHandler = () => {
console.log( "onMouseDownCapture Event!" );
};
return (
<div className= "App" >
<h1> Hey Geek!</h1>
<p onMouseDownCapture={onMouseDownCaptureHandler}>
Click Me!
</p>
</div>
);
} export default App;
