ReactJS has a pretty decent tutorial on their website to get the feel of things! I havent tried the codecademy tutorials but I know they have quite a few free tutorials for web development (JavaScript, Angular, React, Express).
Another approach to web development that one could look into would be the MEAN stack development. This approach consists of utilizing MongoDB (for database usage), ExpressJS (backend interactions), AngularJS (frontend UI usage), and NodeJS (back end server interactions).
