Tried to refactor the code more, is it still good practice or should I rather leave it like it was?

Hi All!

So I Refactored the code more by creating a eventAdder function. My question is would this still be considered good practice or should I rather have not implemented the eventAdder function and just stuck with addEventListener on all elements required?

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


const focusHandler = event => {
  event.target.className = 'highlight';
}
const blurHandler = event => {
  event.target.className = '';
}


function eventAdder (element, event, callback){
  element.addEventListener(event, callback)
};

eventAdder(nameInput, 'focus', focusHandler);
eventAdder(nameInput, 'blur', blurHandler);
eventAdder(messageTextArea,'focus', focusHandler);
eventAdder(messageTextArea, 'blur', blurHandler);
