React Js Count Amount of Filtered Items
React Js Count Amount of Filtered Items:In React.js, counting the number of filtered items involves utilizing state management. First, create a state variable to store the filtered items, typically within a functional component. Apply a filter operation to your data source based on your desired criteria, updating the state variable with the filtered results. Then, simply access the length property of the filtered array to get the count of items that meet the criteria. Ensure that any changes to the filtering criteria trigger a re-render to keep the count up-to-date. Finally, display the count wherever needed in your component's UI, reflecting the number of filtered items dynamically.

How can I count the number of items that match a specific filter in a Reactjs?
This Reactjs code snippet creates a filterable list of items. It initializes with a dataset containing educational institutions categorized as "College" and "School." Users can select a category from a dropdown and click "Apply Filter" to display the items from the chosen category. The code uses React state to manage the selected category and the filtered data. After filtering, it updates the display to show the count of filtered items out of the total items. The filtered items are listed below.
