Full stack development refers to building both the frontend (client side) and backend (server side) of a web application. To develop, manage, and deploy applications efficiently, developers use essential tools like VS Code, Git, GitHub, and Docker. Visual Studio Code (VS Code) is a widely used source code editor that supports multiple programming languages and provides features such as syntax highlighting, debugging, extensions, and an integrated terminal, making coding faster and more organized. Git is a distributed version control system that helps developers track changes in their code, manage different versions, create branches, and collaborate with team members without losing previous work. GitHub is an online platform that hosts Git repositories, allowing developers to store their projects in the cloud, collaborate through pull requests, manage issues, and showcase their work as a portfolio. Docker is a containerization platform that packages applications along with all their dependencies into containers, ensuring the application runs consistently across different environments like development, testing, and production. Together, these tools enhance productivity, teamwork, project management, and smooth deployment in full stack development.
