JSX is not a new development language, but a syntax scheme that Facebook proposes: a syntactic sugar that can write HTML tags directly in JavaScript code, so JSX is essentially a JavaScript language. Tip: syntax sugar (syntactic sugar) is by the British computational scientist Peter Landing (https://zh.wikipedia.org/wiki/%E5%BD%BC%E5%BE%97%C2%B7%E5%85%B0%E4%B8% 81) The invention of a term, refers to a computer language added to a grammar, which has no effect on the function of the langu

React-router provides, props for setting a specific style on a Link component whose path matches our current route. Activestyle allows for a inline style while activeclassname allows for a class defined in an external stylesheet.const Links = () =nav> LinkActivestyle={{color:' Green '} to="/">HomeLink> LinkActivestyle={{color:' Green '} to= "/about">AboutLink> LinkActiveclassname= "Active" to= "/contact">ContactLink> nav>;.

Since React-router routes is components, creating nested routes is as simple as making one route a child of another in JS X.Make the nested component:class App extends React.component { render () { return( "/" component={home}> " About " component={about}> "Contact" component={ contact}> );} }Change the path:ConstLinks = () = 'Green'}} to="/">Home'Green'}} to="/about">About"Acti
