In codepen everything is separated but in your HTML you should put the scripts before the divs.
Something like:
<script>
//blabla.yourscripts - you got it
</script>
<div class="wrapper">
<div class="poll-box">
<div class="poll-container">
<div class="poll-question">Do You Love to Play FreeFire?</div>
<div class="poll-panel row mt-30">
<div class="btn poll-panel-btn" aria-role="button" data-result="0" data-vote="0"> <span>Yes</span></div>
<div class="btn poll-panel-btn" aria-role="button" data-result="0" data-vote="1"> <span>No</span></div>
</div>
</div>
</div>
</div>
So just put the scripts before the stuff reading them.

You have included CP which is the CodePan component.
Please remove window.CP lines, then it will work:
window.CP.exitedLoop(0);
if (window.CP.shouldStopExecution(0)) break;

I'm new to OOP and I'm struggling.
I'm building a library where you can add a book with the title, author nr of pages and if you've read it or not. When I add the first book if I check the box it displays that to book is not read(which is false). When I add a new book the read functionality is not applied to that book at all. I have no idea how to fix it

In this function you are checking the status if isRead which is incorrect.
Do this
Call the readStatus function inside the for loop
Pass the current parameter readStatus(myLibrary[i].checked)
Modify readStatus as shown below
function readStatus(status) {
const bookReadStatus = document.querySelector(".book__read");
if (status) {
bookReadStatus.classList.add("yes");
bookReadStatus.textContent = "I read it";
bookReadStatus.style.color = "rgb(110, 176, 120)";
} else {
bookReadStatus.classList.add("no");
bookReadStatus.textContent = "I have not read it";
bookReadStatus.style.color = "rgb(194, 89, 89)";
}
}

Adding a square root function to a calc using js

So, I made a calculator, and I want to add a square root function, but I know there is no already made function that finds the square root of numbers. So what elements can I combine to find the square root of a number?
const screen = document.querySelector("#screen");
const clearButton = document.querySelector("#clear");
const equalsButton = document.querySelector("#equals");
const decimalButton = document.querySelector("#decimal");
let isFloat = false;
let signOn = false;
let firstNumber = "";
let operator = "";
let secondNumber = "";
let result = "";
const allClear = () => {
isFloat = false;
signOn = false;
firstNumber = "";
operator = "";
secondNumber = "";
result = "";
screen.value = "0";
};
const calculate = () => {
if (operator && result === "" && ![" ", "+", "-", "."].includes(screen.value[screen.value.length - 1])) {
secondNumber = screen.value.substring(firstNumber.length + 3);
switch (operator) {
case "+":
result = Number((Number(firstNumber) + Number(secondNumber)).toFixed(3));
break;
case "-":
result = Number((Number(firstNumber) - Number(secondNumber)).toFixed(3));
break;
case "*":
result = Number((Number(firstNumber) * Number(secondNumber)).toFixed(3));
break;
case "/":
result = Number((Number(firstNumber) / Number(secondNumber)).toFixed(3));
break;
default:
}
screen.value = result;
}
};
clear.addEventListener("click", allClear);
document.querySelectorAll(".number").forEach((numberButton) => {
numberButton.addEventListener("click", () => {
if (screen.value === "0") {
screen.value = numberButton.textContent;
} else if ([" 0", "+0", "-0"].includes(screen.value.substring(screen.value.length - 2))

} else if ([" 0", "+0", "-0"].includes(screen.value.substring(screen.value.length - 2))

} else if (result || result === 0) {
allClear();

} else {
screen.value += numberButton.textContent;
}
});
});

screen.value += ".";
} else if (!isFloat) {

} else if (operator && ![" ", "+", "-", "."].includes(screen.value[screen.value.length - 1])) {

This is the code for the calc.. Feel free to edit it and explain to me what you did.

There is already one.
The Math.sqrt() function returns the square root of a number, that is, ∀x≥0,Math.sqrt(x)=x
=the uniquey≥0such thaty2=x
MDN Docs

You can use javascript built in
Math.sqrt(number)

Javascript - Some errors in my LocalStorage script

I am a newbie in JS (level 0), and although I try to store all the variables of my practice in Local Storage, I am doing something wrong, because when reloading the page many functions (previously visible), now disappear in the reload.
SEE LIVE DEMO
Where is my errors...?
What am I doing wrong...?
Thanks in advance!

Adding an extra two variables to a count simulator function

I've created the following fiddle https://jsfiddle.net/jnoweb/v421zzbe/2/
At the moment it has one variable which makes all three IDs count up to 20:
var game = {score:0},
scoreDisplay = [
document.getElementById("score1"),
document.getElementById("score2"),
document.getElementById("score3")];
function add20() {
TweenLite.to(game, 1, {score:"+=20", roundProps:"score", onUpdate:updateHandler, ease:Linear.easeNone});
}
function updateHandler() {
scoreDisplay.forEach(function(display) {
display.innerHTML = game.score;
});
}
add20();
I want to change this so that each ID counts to a different value, for example 16, 18 and 20!
Does anyone know how to achieve this?

Here is the more elegant, generic, configurable solution.
function ScoreDisplay(id, increment) {
this.elm = document.getElementById(id);
this.inc = increment;
this.game = {score: 0};
}
ScoreDisplay.prototype = {
update: function(){
this.elm.innerHTML = this.game.score;
}
};
var scoreDisplay = [];
scoreDisplay.push(new ScoreDisplay('score1', 16));
scoreDisplay.push(new ScoreDisplay('score2', 18));
scoreDisplay.push(new ScoreDisplay('score3', 20));
function addScore() {
scoreDisplay.forEach(function(sd) {
TweenLite.to(sd.game, 1, {score: "+=" + sd.inc, roundProps:"score", onUpdate:sd.update.bind(sd), ease:Linear.easeNone});
});
}
addScore();
#score1 {
position: relative;
font-size: 30px;
font-weight: bold;
padding: 20px;
text-align: center;
background-color: transparent;

text-align: center;

border-radius: 20px 20px;
top: -11px;

}
#score3 {

font-weight: bold;
padding: 20px;
text-align: center;

var key = ("score" + (i+1))

}

What about this ?

}
function updateHandler() {
scoreDisplay.forEach(function(display, key) {
var score = scoreDisplay[key].id;
display.innerHTML = game[score];
});
}
add20();
