Document Object Model

The DOM is an object orientated representation of the document (or page) in memory
The browser reads the HTML file and identifies all the dependencies
Any external dependencies have to be requested from the server before it can build the DOM
The DOM represents the document structure, style and content
The contents of the DOM can be modified using an API
The browser uses the DOM and the standard APIs to allow the web page to be accessible from an ECMAScript scripting language (or JavaScript).
The following are examples of common APIs:
document.getElementById
element.innerHTML
window.onload
console.log
