What are Frontend Libraries

Frontend libraries are collections of pre-written code and functionalities that developers can use to enhance the user interface (UI) and user experience (UX) of websites and web applications. These libraries are written in programming languages like JavaScript, HTML, and CSS and are designed to simplify common frontend development tasks.

Developers can choose the library that best suits their project's requirements and integrate it into their codebase to speed up development and improve the overall quality of their web applications.
