Window Object
For understanding the concept of BOM and DOM first we need to understand about window object. All objects, functions, and variables are a part of the window object.Both BOM and DOM are window objects.
BOM
BOM stands for Browser Object Model. The BOM is the window object that represents a window in the browser. We can manipulate the browser window with the window object and add various events using BOM properties. The DOM is a subset of BOM object and we can access DOM by using document properties and methods. Apart from document BOM also have history, screen, location etc.
DOM
It stands for Document Object Model. Document Object Model in JavaScript is used to access the elements inside the document. It maps the entire Document into a hierarchy of parent and child in tree structure along with its properties and methods. The document object represents the whole HTML document. When an HTML document is loaded in the browser, it becomes a document object, and you can use document object to manipulate the web page.
We can change an element's text, element's color, hide and show elements, add an event listener to the HTML elements etc.
