What is a tech stack?

A tech stack refers to the combination of technologies, including programming languages, frameworks, libraries, databases, and tools, that are used to build and run an application or project. It typically includes both frontend and backend technologies, as well as any supporting infrastructure. Companies choose specific tech stacks based on the needs of the project, scalability, and the expertise of their development teams. Understanding a tech stack is important for developers to effectively collaborate and maintain software systems.
