Instead of using an arrow function with an event parameter that calls upon event.currentTarget, couldn’t I instead write a function that uses $(this)? They both seem to work, but is one preferred over another?

  $('.product-photo').on('mouseenter', event => {
    $(event.currentTarget).addClass('photo-active')
  }).on('mouseleave', event => {
    $(event.currentTarget).removeClass('photo-active')
  })
  $('.product-photo').on('mouseenter', function () {
    $(this).addClass('photo-active');
  }).on('mouseleave', function () {
    $(this).removeClass('photo-active');
  })

An author may prefer one over the other but there is no industry standard that says we need to choose one over the other (that I am aware of). It’s possible the lesson author was presenting this as the alternative approach. We know that arrow functions do have this locally so the only means of accessing the event object is through the parameter, which has a currentTarget attribute we can poll.

Bottom line, write with consistency, meaning use one approach or the other, not both as this will only help to confuse things.
