DOM stands for Document Object Model is an interface (API) for HTML and XML documents. When the browser first reads (parses) our HTML document it creates a big object, a really big object based on the HTML document this is the DOM. It is a tree-like structure that is modeled from the HTML document. The DOM is used for interacting and modifying the DOM structure or specific Elements or Nodes.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document Object Model</title>
</head>
<body>
<div>
<p>
<span></span>
</p>
<label></label>
<input>
</div>
</body>
</html>
The document object in JavaScript represents the DOM. It provides us many methods that we can use to selecting elements to update element contents and many more.
