React Js Scroll Indicator
React Js Scroll Indicator | Progress bar:A React.js scroll indicator is a user interface element used to visually indicate the position and progress of scrolling within a web page or component built with the React.js library. It typically appears as a bar, line, or some visual cue that fills or moves as the user scrolls through content. This helps users gauge their location within a lengthy page and how much more content remains to be seen. React.js scroll indicators are implemented using CSS and JavaScript to track scroll events and update the indicator's appearance dynamically, enhancing the user experience by providing context and navigation cues during scrolling.

How can a scroll indicator be implemented in Reactjs for tracking user's page progress?
This React JS script creates a scroll indicator component. It tracks the user's scroll position and displays a progress bar to indicate how far they've scrolled down the page. The useState hook is used to manage the scroll percentage state, and the useEffect hook adds a scroll event listener. As the user scrolls, it calculates the scroll percentage based on the current scroll position relative to the page height and updates the state accordingly. The progress bar's width is dynamically set based on the scroll percentage. This component enhances user experience by providing a visual indicator of their scroll progress.
