How can pass params in React-Router

Question

I use React with React Router and I have 3 links which has same path as component. How can I pass different params on click to component?

const Example = props => {
  console.log("props", props);

  return (
    <div className="App">
      <h1>Hello CodeSandbox</h1>
      <h2>Start editing to see some magic happen!</h2>
    </div>
  );
};

function App() {
  return (
    <BrowserRouter>
      <Switch>
        <Route path={"/example"} render={() => <Example />} />
      </Switch>
      <>
        <Link to={"/example"} params={{ name: "john" }}>
          <button>name</button>
        </Link>
        <Link to={"/example"} params={{ age: "27" }}>
          <button>age</button>
        </Link>
        <Link to={"/example"} params={{ surname: "Travolta" }}>
          <button>surname</button>
        </Link>
      </>
    </BrowserRouter>
  );
}

Your improved code

const Example = props => {
  console.log("props", props);

  return (
    <div className="App">
      <h1>Hello CodeSandbox</h1>
      <h2>Start editing to see some magic happen!</h2>
      <Link to={{ pathname: "/Example2", state: { name: "Hello world..." } }}>
        Navigate to Example2
      </Link>
    </div>
  );
};
const Example2 = props => <h1>Hey...{props.location.state.name}</h1>;
function App() {
  return (
    <BrowserRouter>
      <Switch>
        <Route path={"/example"} render={() => <Example />} />
        <Route path={"/Example2"} render={Example2} />
      </Switch>
      <>
        <Link to={"/example"} params={{ name: "john" }}>
          <button>name</button>
        </Link>
        <Link to={"/example"} params={{ age: "27" }}>
          <button>age</button>
        </Link>
        <Link to={"/example"} params={{ surname: "Travolta" }}>
          <button>surname</button>
        </Link>
      </>
    </BrowserRouter>
  );
}

This is how can pass properties through Link

   <Link to={{ pathname: "/Example2", state: { name: "Hello world..." } }}>
       Navigate to Example2
   </Link>

and access like this in navigated component if it's functional component

props.location.state.name

if class based component

this.props.location.state.name

You can use the to property of Link, and access the state in Example component with props.location.state.

import React from "react";
import ReactDOM from "react-dom";
import { BrowserRouter, Switch, Route, Link } from "react-router-dom";
import "./styles.css";

const Example = props => {
  console.log("props", props.location.state);

  return (
    <div className="App">
      <h1>Hello CodeSandbox</h1>
      <h2>Start editing to see some magic happen!</h2>
    </div>
  );
};

function App() {
  return (
    <BrowserRouter>
      <Switch>
        <Route path="/example" component={Example} />
      </Switch>
      <>
        <Link to={{pathname:"/example", state: {name: "john"}}} >
          <button>name</button>
        </Link>
        <Link to={{pathname:"/example", state: {age: "27"}}} >
          <button>age</button>
        </Link>
        <Link to={{pathname:"/example", state: {surname: "Travolta"}}}  >
          <button>surname</button>
        </Link>
      </>
    </BrowserRouter>
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
