Yarn (JavaScript Package Manager)

Yarn is a package manager for JavaScript projects that helps developers install, update, and manage third-party dependencies. It works with the npm package registry and uses project files to keep dependency versions consistent across development, testing, and production environments.

Yarn provides features such as dependency locking, workspaces for monorepos, caching, and deterministic installations. It is commonly used in Node.js, React, and other JavaScript-based projects where reliable dependency management is important for repeatable builds.
