React Js Get Screen width and Height
React Js Get Screen width and Height :In React.js, you can obtain the screen width and height using the window object. To get the screen width, you can access window.innerWidth, and to get the screen height, you can use window.innerHeight.
These properties return the viewport dimensions in pixels. You can retrieve these values and use them within your React components to perform responsive actions or dynamically adjust the layout based on the screen size.
Keep in mind that accessing the window object directly in React components may not work during server-side rendering, so you may need to handle that scenario separately.

How can I retrieve the screen width and height using React.js?
This React.js code snippet demonstrates how to get the screen width and height and display them in a component. The code uses React hooks, specifically the useState and useEffect hooks.
First, two state variables, screenWidth and screenHeight, are initialized using the useState hook. They are initially set to the current window's inner width and inner height, respectively.
A handleResize function is defined to update the state variables whenever the window is resized. It gets the updated inner width and height and sets them using the setScreenWidth and setScreenHeight functions.
The useEffect hook is used to add an event listener for the 'resize' event when the component is mounted. This ensures that the handleResize function is called whenever the window is resized. The hook also returns a cleanup function that removes the event listener when the component is unmounted.
Finally, the component renders a container div with headings displaying the purpose ("React Js Get Screen width and height") and paragraphs showing the screen width and height values, which are dynamically updated based on the window size.
