This is pwa quiz app, I have used React JS, Typescript, Rest API, HTML5, CSS, Bootstrap4. Progressive web apps are just like native apps we can install it on mobiles or desktop and just run by clicking on its icon. It cache file and will also be available if you are offline mean without internet. In this quiz app user just choose the answer and if the answer will be correct then score will be added with refreshing page because of local storage management. After completing of quiz you can see total scores on screen.
