In this kit, we're going to see how to Show Answers from list when click on questions using Reactjs with simple steps.The purpose of a FAQ is generally to provide information on frequent questions or concerns; however, the format is a useful means of organizing information, and text consisting of questions and their answers may thus be called a FAQ regardless of whether the questions are actually frequently asked.In ReactJS, changing items in the list when an item of the list is clicked can be done by triggering the event onClick() on the item which is currently clicked. For, reflecting the change, we also have to maintain the state in react so that after change when the page render again the changes get reflected.
