How to Scroll to Specific Element in React?
React Js Scroll to Element by id:To scroll to an element by its ID in React.js, you can follow these steps. First, use the useRef hook to create a reference to the element with the specified ID. Next, add an event listener, such as a button click, and define a function to handle the scrolling. Inside the function, use the scrollIntoView method on the element's current property to scroll to it. Finally, call the function when the event occurs. This approach allows you to scroll to a specific element on the page based on its ID using React.js.

How do you scroll to the last item in a list using a ref in Reactjs?
This React.js code defines a component that displays a list of items and provides two buttons: "Scroll to Last Item" and "Show More Items." It uses hooks like useState and useRef. The state variable itemsToShow controls how many items are displayed, and it initially shows 5 items. Clicking "Show More Items" increments the count.
The scrollToLastItem function uses useRef to reference the last item in the list and scrolls to it smoothly when the "Scroll to Last Item" button is clicked. This provides a user-friendly scroll behavior.
Overall, the code dynamically manages item visibility and provides a convenient way to scroll to the last item in the list.
