Yarn package manager

Yarn is a tool used to manage software libraries and dependencies for projects, similar to a library organizer. When developers build applications, they often rely on external code packages to add features quickly. Yarn helps automatically download, update, and keep these packages organized and consistent across different environments. It ensures that all team members use the same versions, reducing errors. Think of it as a smart assistant that keeps all the necessary tools and components in order, making software development faster, more reliable, and easier to maintain.
