Objects to contain variables in - JavaScript

Is it a good idea to create an object in JavaScript to contain variables for all the elements of a particular section of HTML document you are working with, just for the purpose of keeping it clean?

So for example, suppose the following basic HTML code, imagine you are working on a form (i havent added anything semantic just keep it simple):

<form id="user-form">
  <input type="text" id="first-name">
  <input type="text" id="second-name">
  <input type="email" id="email">
  <textarea id="user-text></textarea>
</form>

const form_object = {
  first_name: document.getElementById("first-name"),
  second_name: document.getElementById("second-name"),
  email: document.getElementById("email"),
text: document.getElementById("user-text")

}

It probably depends on what you intend to do with these items, you might not need separate variables defined for each element. And remember, the DOM is already structured so that you can access the contained elements using traversal methods. For example:

const form_object = document.getElementById("user-form");
let first_name = form_object.firstElementChild;
