Question 1

in js forms, what is the name attribute in tags for?

how do you use the “required” attribute for forms?

Answer 2

just type required. no value is needed.

e.g.

<textarea>
</textarea>

Question 3

what does this do:

$newObj.title = document.forms[0].elements.title.value;

And what does the [0] here do instead of “title”?
$newObj.title = document.forms[0].elements[0].value;

Answer 3

the value of the element with the name “title” among elements within the first form (index 0) on the document is is being set as the title variable within the $newObj.

they both do the same thing except the second is searching by index instead of the “name” attribute
