Full-stack development is like being a one-person team that can handle everything in a restaurant, from greeting the guests to cooking the meals. In the web world, a full-stack developer is someone who knows how to do both front-end and back-end development. They work on the front-end, which is everything users see on a website, like the layout, design, and interactive parts. This involves using HTML, CSS, and JavaScript to make the website look good and be easy to use. Then, they also handle the back-end, which is all the stuff that happens behind the scenes, like storing data in databases and making sure the server, which hosts the website, runs smoothly. A full-stack developer has the skills to create a complete website from start to finish. They can set up the server, organize the data, and make sure the website's design and functionality work well for the users.
