Why doesn't it work?
When I use this code in the code playground it only works when I paste it under <script> tag in HTML. But when I paste it in the JavaScript tab, it gives me an error. what am I missing? html tab: <p id="demo"></p> JavaScript tab: var text = document .getElementById("demo"); text.innerHTML = "hello world";

Wrap your code in:
window.onload = function(){}
I think it’s because the script loads before HTML

This is how it looks and still doesn't work.

Ahah you didn’t understand ^^
This:
window.onload = function(){
function hmm (){
var test = document .getElementById("demo");
test.innerHTML = "HELLO";
}
}

hmm is not defined.

Because window.onload will execute the code after the HTML document has loaded.
If not, js will not recognize your html elements.

Yeah, but it’s not very easy to read it

There is no output now. I still am doing something wrong.

No, just need to call your function, like this: hmm();

Call it after your function’s declaration

now it worked. but why do I have to call it within a window.onload scope?

This is why it's recommend to put your JS at the bottom of the <body> tag.

Wouldn't this be an easier way to go?

Kacper Orłowski the 2nd value the code asks is used as value for your progress bar.
Why do you say it's not working?
