Web Development is about building web applications that can run in a browser such as Chrome or Firefox. Full-stack means building both the frontend and the backend systems of any application. The frontend is what users see on the screen when they open a website or a web application. Backend represents the server-side to which this frontend connects to and gets the data for you.
Any food delivery or cab booking applications such as Zomato, Paytm are prime examples of these. When you load the website you see fixed content but once you login to the application it is able to get your information from the backend and show this unique information as well.
In this course, you will start from the very basics of programming and go all the way to building similar full-stack applications using the latest technologies like React.js and Node.js.
