Mix is the build tool for Elixir, providing tasks for creating projects, compiling code, running tests, and managing dependencies efficiently.

Mix is an integral part of the Elixir development ecosystem, serving as the official build tool and project management system. It simplifies many aspects of the development process, allowing developers to focus on writing code rather than managing configurations. With Mix, you can create new projects using the command mix new project_name, which automatically generates a directory structure and essential files like mix.exs. This file defines the project, its dependencies, and configurations. Mix handles dependency management efficiently; you can declare dependencies in mix.exs and use commands like mix deps.get to fetch them. Furthermore, Mix provides a range of tasks for compiling code (mix compile), running tests (mix test), generating documentation (mix docs), and even creating releases for deployment (mix release). Additionally, developers can define custom Mix tasks to automate repetitive tasks tailored to their projects. Overall, Mix streamlines the development workflow, making it easier to manage projects and dependencies in Elixir.
