Toggle Javascript
Greetings, everyone! It's been years since I've written a piece of code, so I thought I'd give it a try. I'm pretty sure I know how to write a toggle function, so I'm curious as to why these two examples don't work. https://sololearn.com/compiler-playground/W639upiF8RJ5/?ref=app

The screenC variable is not an html div element, as you might think, it's just a regular string variable that stores the name of the color.
So you need to assign it to the html element at the end of the condition:
screen.style.backgroundColor = screenC;
An example of how the .toggle() method works:

Yeah, I'm definitely rusty. Especially now, when there are a lot of easier ways to do this. Thank you so much for your help!

Function toggle(el) {
// Disactive
el.style.display = "none";
// Active
el.style.display = "block"; //flex, inline, inline-block
}
