How do I determine height and scrolling position of window in jQuery?

I need to grab the height of the window and the scrolling offset in jQuery, but I haven't had any luck finding this in the jQuery docs or Google.

I'm 90% certain there's a way to access height and scrollTop for an element (presumably including the window), but I just can't find the specific reference.

From jQuery Docs:

const height = $(window).height();
const scrollTop = $(window).scrollTop();

http://api.jquery.com/scrollTop/
http://api.jquery.com/height/

from http://api.jquery.com/height/ (Note: The difference between the use for the window and the document object)

$(window).height();   // returns height of browser viewport
$(document).height(); // returns height of HTML document

from http://api.jquery.com/scrollTop/

$(window).scrollTop() // return the number of pixels scrolled vertically

Pure JS

window.innerHeight
window.scrollY

is more than 10x faster than jquery (and code has similar size):

Here you can perform test on your machine: https://jsperf.com/window-height-width

$(window).height()

$(window).width()

There is also a plugin to jquery to determine element location and offsets

scrolling offset = offsetHeight property of an element

If you need to scroll to a point of an element. You can use Jquery function to scroll it up/down.

$('html, body').animate({
                scrollTop: $("#div1").offset().top
            }, 'slow');
