target refers to the DOM element that triggers an event. Otherwise, currentTarget refers to the DOM element that the event listener is listening on.

<ul class="todo-list">
  <li class="item">Walk your dog</li>
</ul>

const list = document.querySelector(".todo-list");

list.addEventListener("click", e => {
  console.log(e.target);
  // Output: <li class="item">Walk your dog</li>
  console.log(e.currentTarget);
  // Output: <ul class="todo-list"></ul>
});
