JavaScript Callback Functions in JavaScript Callbacks and the DOM Using the Same Callback on Multiple Elements

Is this code ok..?

// my version (it's shorter but not sure if better or worse):


const nameInput = document.getElementById('name');
const messageTextArea = document.getElementById('message');


const focusAndBlur = (element) => {
  element.addEventListener("focus", (e) => e.target.className = 'highlight')
  element.addEventListener("blur", (e) => e.target.className = '')
}

focusAndBlur(nameInput);
focusAndBlur(messageTextArea);
