A tech stack is a combination of tools and technologies used to build and run an application. It includes:
Frontend (Client-side): Technologies like HTML, CSS, and JavaScript that control what users see and interact with.
Backend (Server-side): Technologies like Python, Node.js, and databases (e.g., MySQL) that handle data processing and storage.
Additional Tools: Tools for version control (e.g., Git), deployment, and cloud services (e.g., AWS).
The tech stack is chosen based on the project’s needs and helps developers create and manage applications.
