I love JQuery, I do, but just for fun I'd like to learn how to write the following in pure/vanilla JS.
$("iframe").contents().find("<style>").html(cssEditor.value))
Something like this should work:
document
.getElementsByTagName('iframe')[0]
.contentDocument
.getElementsByTagName('style')[0]
.innerHTML = cssEditor.value;
Use the contentDocument property of the <iframe> DOM object to get the inner document.
You can then call normal methods on it like querySelector.

Is it advisable to manipulate the parent of the DOM that is body element manually in React just like we do in vanilla JS?
Like is it good practice to do like this because here I am not manually manipulating DOM, but instead manipulating it parent element?
document.body.style.overflow = "hidden"
In my experience: It's ok to do this.
Often this sort of thing is done when opening Modals (like Bootstrap)
It's a valid thing to do.

Hi lets assume i have a custom variable in the browser."Custom variable" Is it possible to get it with webdriverIO with the browser.execute() method?
Yes, it's possible with js.

Suppose I have an HTML element (like a <div>). Is there a way to duplicate it after a click using JavaScript?
If yes, is it possible to change the content of the duplicated HTML element to something else?
EDIT: Yes, I was asking how to do it as well. Thanks to the guys who answered my question!
You can use Node.cloneNode() on original element, set Elment.innerHTML of cloned node.
a
<script>
var clone = document.querySelector("a").cloneNode();
clone.innerHTML = "b";
document.body.appendChild(clone);
</script>
See clone.
$('a').clone().html("something else");

I have a CoffeeScript code that looks like this:
if $('#user_address_attributes_country').val() == ""
$('#user_address_attributes_country').val("PL")
Now I want to do the same thing for a few divs but without repetitions.
How can it be done by jQuery?
The reason you can't apply it multiple times is because your trying to apply it to an element which has an id. They are unique. Use classes and do this instead:
if ($('.user_address_attributes_country').val("")) {
$('.user_address_attributes_country').val("PL");
}

I am trying to change CSS elements depending on situations used in javascript.
an example I had tried was:
if ('image'=="clicked")
{blahblahblah}
'image' would be my div id or div tag in CSS.
I know in Jquery I can use $('#image').click, but I don't think it Jquery will be good for my situation.
Consider document.querySelector. It's powerful, accepting any valid CSS selector. You can even start from another element, such as myElement.querySelector, to only get children of that element that match the selector. Very useful!
Just be aware that IE7 and below do not support this function.
Assuming your id as image
document.getElementById('image').onclick = function() {
alert("button was clicked");
};
