What is the difference between dom and javascript

Saying it simpler, an element is a subtype of a node the same way a cat is a subtype of an animal. Aside from differentiating nodes from elements, you need also to distinguish the DOM properties that contain specifically only nodes, or only elements. The following properties of Node type evaluate to a node or a collection of nodes NodeList :.

Since both node. Good question! Open the demo , then look at childNodes and children properties of the parapgraph node:.

However, paragraph. Because paragraph. Having both node. A DOM document is a hierarchical collection of nodes. Element inherits from the generic Node interface, and together these two interfaces provide many of the methods and properties you use on individual elements. These elements may also have specific interfaces for dealing with the kind of data those elements hold, as in the table object example in the previous section. When a member returns an object of type document e.

The DOM document Reference chapter describes the document object. Every object located within a document is a node of some kind. In an HTML document, an object can be an element node but also a text node or attribute node. The element type is based on node. Rather than saying, for example, that the document. A nodeList is an array of elements, like the kind that is returned by the method document. Items in a nodeList are accessed by index in either of two ways: list. In the first, item is the single method on the nodeList object.

The latter uses the typical array syntax to fetch the second item in the list. When an attribute is returned by a member e. Attributes are nodes in the DOM just like elements are, though you may rarely use them as such. A namedNodeMap is like an array, but the items are accessed by name or index, though this latter case is merely a convenience for enumeration, as they are in no particular order in the list.

A namedNodeMap has an item method for this purpose, and you can also add and remove items from a namedNodeMap. And for DOM you can manipulate html elements with javascript. Essentially, it connects web pages to scripts or programming languages While JavaScript is the programming language which will allow you to operate on the DOM objects hope that clears it up.
