Whats the effects of shortening form.elements.name to form.name?

I am working with many forms in single page but I'd prefer using short notation form.name instead of form.elements.name Is there any issues if I keep shortening?

Most times there is no problem in using shorter notation since we rarely need to change name attribute in forms. But there is a little issue if we eventually change our name attribute. The problem is that both old name and new name will still be available and may lead to confusion. Lets have an example:

<form id="testform">
  <input name="fname" placeholder="Name">

  testform.fname.name = "newname"; // changed
  console.log(form.elements.fname); // undefined
  console.log(form.elements.newname); // input
  console.log(form.fname == form.newname); // true

Initially, testform.elements.fname is equal to testform.fname but after changing it to newname, testform.elements.fname becomes undefined and testform.elements.newname gives output we want. Good thing, when you compare both new name and old name, they are equal because forms allow both. »
