React is a JavaScript library developed by Facebook to create UI. It provides a great starting point with a lot of components and styles, letting you rapidly develop applications for both any screen size and offering the capability to proceed with fully custom elements if necessary.

All React UI libraries have been developed from scratch with the specification that they work on all browsers, unlike most other UI frameworks that offer limited browser compatibility.

What are UI libraries?

They are toolkits used to make designer's lives easier. They provide component libraries of pre-made items for users to use in building their projects like menus, buttons, alerts, etc. The plugins also reduce the need of designing every single element on the page which saves time and helps avoid frustrating situations for our visual designers.

5. Semantic UI React

Semantic is a development framework that helps create beautiful, functional layouts using human-friendly HTML.

Semantic UI treats words and classes as the same thing. Classes use syntax from natural languages like noun/modifier relationships, word order, and plurality to link concepts intuitively.

Semantic uses easy phrases called behaviors that trigger functionality. Each behavior is a setting in a component that developers can modify.

Conclusion

The most interesting thing about React UI libraries is that they are open-sourced projects, meaning that you have the liberty to choose the best or use it with your web design, or even create an entirely new one.
