Depending on what you want to do here, you might find the :local-link pseudo-class useful to be able to do styling directly in the CSS without needing to change the class name in React

the part between {} is just a javascript expression. You can use a template string:

<Link to="/" className={`${(pathname === '/') ? 'active' : ''} yourClass`} ><li>Home</li></Link>

<Link to="/" className={`${(pathname === '/') ? 'active' : ''} yourClass`} ><li>Home</li></Link>

or an array if you don't like template strings:

<Link to="/" className={[(pathname === '/') ? 'active' : '', 'yourClass'].join(" ")} ><li>Home</li></Link>

<Link to="/" className={[(pathname === '/') ? 'active' : '', 'yourClass'].join(" ")} ><li>Home</li></Link>

In react you use className, with the camelCase. classname without the capital letter is html, so react uses className.

Better method is to use the aria attribute vs using a class.
