 45. ### Why React uses `className` over `class` attribute?
 
-    `class` is a keyword in JavaSript, and JSX is an extension of JavaScript. That's the principal reason why React uses `className` instead of `class`. Pass a string as the `className` prop.

 301. ### Is it recommended to use CSS In JS technique in React?
-     React does not have any opinion about how styles are defined but if you are a beginner then good starting point is to define your styles in a separate *.css file as usual and refer to them using className. This functionality is not part of React but came from third-party libraries. But If you want to try a different approach(CSS-In-JS) then styled-components library is a good option.
