try is yourself

open the console of your browser right now. press ctrl + shift + j enter this in the console of your browser.

console.log(document);

what do you get? you will get the entire HTML document returned. here the document object represents the entire web page.

if we want to access any element in the web page we need to start accessing that with the help of the document object.

for example, if you want to get the domain of the page ... just type

console.log(document.domain)

How can I manipulate dom?

well, there are many many ways to do that... you can use query selectors, getElement by class, or id

 document.querySelector(".myclass");
var x = document.querySelectorAll(".myclasses");

// if I want to change the background...
x.style.backgroundColor = "dark" ;

this is how you can easily manipulate dom.
