How can ReactJS display items based on their respective categories?

edit

ReactJS can display items based on their respective categories by filtering them based on the category parameter. This can be done in several ways:

1. Using Array.filter() method: This method filters the array based on a condition and returns a new array that meets the condition. We can use it to filter items based on their category.

2. Using conditional rendering: This approach involves writing a logic to render items based on their category. We can use an if-else statement or a switch statement to render items based on their category.

3. Using ReactJS libraries: There are several ReactJS libraries that we can use to filter and display items based on their category. Some popular ones include react-filter-search and react-sortable-tree.

Overall, the approach will depend on the specific requirements of the project, but these are some common ways to display items based on their respective categories in ReactJS.
