Polygon Stocks App simulates a list of frequently updating stock tickers. This app demonstrates how memoization can be used to control unnecessary re-renders of components where data has not changed. It also illustrates how infinite scroll can be used to increase performance, specifically when calculating 'First Contentful Paint'.
