What is the DOM and BOM in JavaScript?

Question

What is the DOM and BOM in JavaScript? If someone could explain these in layman terms it would be great! I like to get a deeper understanding of these.

Answer 1

DOM means Document Object model..when the webpage is loaded the browser creates a document object model for the page..All the objects are arranged as tree structure...

BOM means Browser Object Model.window object is supported by all browsers it represents the window browser..All global JavaScript objects, functions, and variables automatically become members of the window object.
