what is speed JS or JQ

[KPZ]

Hey guys what is the fastest one from jQuery and JavaSript?

most of the time JS has the fastest single execution
for an example :-

document.getElementById('id_name') > $('#id_name')
first on is faster than second one.

But what do you think,
when we consider about overall performance..
what is the fastest one?

Thanks machan.. I saw this one. This is about for the one execution. I wanna know what is the difference between overall performance.

JS.

JQ is created using JS (JQ is a JS Library).
JQ is easy to use but JS is fast.

i.e : internally $('#id_name') calls document.getElementById('id_name').

It seems JS is faster

we use this method to change the background-color from jQ

$('body').css('background', '#ccc');

so what this calls internally?

document.getElementsByTagName("body")[0].style.backgroundColor = "#ccc";

I have no idea.......
can we do this from single line?

document.getElementsByTagName("body")[0].style.backgroundColor = "#ccc";

This means? what do you wanna do?

You can change the body background color like that by using pure JavaScript

jQuery is a JS framework. How can a framework perform faster than its host language?

ado patta.. it's working.......

ya that's what I wanna know. We can write fewer lines from jQ
so I wanna know about performance

Why bother too much about the speed as the devices nowadays are really fast enough to execute everything too fast. So you won't even notice the distinction between the two. We should only care too much about the speed when we are working on too much logic and loops.

(My personal opinion only)

Accessing DOM is always slow compared to other arithmetic funcs machan. Access them as few as possible, and reuse the selected objects in OO fashion.

If you mess with the code, JQ will have more performance than your pure JS code Normally I use JQ and my clients does not care that whether it's JS or not

ya that's what this site shows

jump into DOM and selecting elements really slow in jQ

machan this also works
document.body.style.backgroundColor="#ccc";
