Скачать или смотреть What is Open Source library

An open-source library is a collection of pre-written code (functions, classes, tools, or modules) that developers can use in their own projects, and its source code is publicly available for anyone to view, use, modify, and share.

Open source → The source code is freely accessible.

Reusability → Saves developers time by providing ready-made solutions (e.g., math functions, data analysis tools, UI components, etc.).

Community-driven → Often maintained and improved by a community of developers worldwide.

Free to use → Most open-source libraries are free, though some may have restrictions based on license type.

👉 In short: an open-source library is like a toolbox of reusable code made freely available for developers to build software more efficiently.
