The NodeList.length property returns the number of items in a NodeList.

MDN Reference

value: string

If the underlying element collection contains radio buttons, the RadioNodeList.value property represents the checked radio button. On retrieving the value property, the value of the currently checked radio button is returned as a string. If the collection does not contain any radio buttons or none of the radio buttons in the collection is in checked state, the empty string is returned. On setting the value property, the first radio button input element whose value property is equal to the new value will be set to checked.

MDN Reference

  • Returns a node from a NodeList by index. This method doesn't throw exceptions as long as you provide arguments. A value of null is returned if the index is out of range, and a TypeError is thrown if no argument is provided.
