How to use Function Components in React TypeScript

// Function Component ( with props and default props ):

import React from "react";

type Props = {

  linkFirst: string,

  routeFirst: string,

  head?: string,

  linkSecond?: string,

  routeSecond?: string

};
/* Default props appear when no value for the prop 
is present when component is being called */

const DefaultProps = {
  head: "Navbar Head not found"
};

const Navbar: React.FC <Props> = (props) => {
  return (
	<div>
		<nav>
		{ props.head }
			<ul>
			<li> 
			<a href={ props.routeFirst }> {props.linkFirst} </a>
			<li> 
			<a href= { props.routeSecond }> {props.linkSecond} </a>
			</li>
   			</ul>
		</nav>
	</div>
  );
};
/* Initializing DefaultProps constant to defaultProps 
so that this constant works. */

Navbar.defaultProps = DefaultProps;
export default Navbar;
