Each of these libraries has a different style and a wide range of features and components.
In order to properly use each library, you need to review their docs. The docs will give you instructions on how to properly set up your app to use the library and will also show examples of how each feature/component is implemented.
Not strictly a react library, but rather uses a common stylesheet and you just add special classes defined in the docs to your code
Can also be used with plain HTML
When using React apps, referencing the bootstrap JS code including Jquery is highly discouraged because it doesn't play nice with React and will likely introduce strange bugs into your app
