Parameters in a JSX function

Let our function showMess take as a parameter the name of the person we want to greet:

jsxfunction showMess(name) {
  alert('hello, ' + name);
}

We can pass this parameter when binding a function to an event. To do this, we should wrap our function call in an arrow function:

jsxfunction App() {
  function showMess(name) {
    alert('hello, ' + name);
  }
  
  return <div>
    <button onClick={() => showMess('user')}>show</button>
  </div>;
}

This way we can bind the same function to several buttons with different parameters:

jsxfunction App() {
  function showMess(text) {
    alert(text);
  }
  
  return <div>
    <button onClick={() => showMess('user1')}>show1</button>
    <button onClick={() => showMess('user2')}>show2</button>
  </div>;
}

jsxfunction App() {
  return <div>
    <button>act1</button>
    <button>act2</button>
    <button>act3</button>
  </div>;
}
