How to .appendChild() to all elements with the same class

The blue F turns into an actual amount of weight when you enter a number into the input field above.
The Two Functions Kg() and Lbs() are changing the class .dynamic which is where Kg or Lbs is being appended to the 8 divs that have the .dynamic class. Now that's exactly what isn't happening. When I select the divs with the .dynamic class, It adds Kg or Lbs (whatever button I press) to the first element with the .dynamic class.
How do I make it so that it appends that to all of the elements with the .dynamic class?

Select all elements with the .dynamic class by using querySelectorAll
Iterate through the NodeList and append desired child to each node
let dynamics = document.querySelectorAll(".dynamic")
dynamics.forEach((ele) => {
let newElement = document.createElement("h3");
ele.appendChild(newElement);
}

Minor Problems
There's no such HTML element <navbar>, there's <nav>.
There's a block code hard-coded 8 times with the only difference between them is a number. Whenever code needs to repeat itself, we use some sort of iteration such as a for loop or an array method and the numbers would be passed as a single variable passed with every iteration.
const gforce = [0.38, 0.9, 1, 0.38, 2.36, 0.92, 0.89, 1.12];
for (let i=0; i < 8; i++) {
var val = weight.value;
console.log(val);
var calculate = val * gforce[i];//<== that should be a variable
calculate = Math.round(calculate);
venus.innerHTML = calculate;
console.log(calculate);
}
Also, the <input> that's supposed to calculate lbs and kg doesn't appear to convert kg to lbs or vice-versa.
Details are commented in example
// An array of objects - each object represents a planet
const data = [{

The script must look something like this:
<script>
let elements = document.querySelectorAll(".dynamic")
elements.forEach(el=>{
let child = document.createElement('div')
el.appendChild(child)
})
</script>

This can be simplified quite a bit, the buttons' innerHTML values match what you want in the new unit elements.
<button id="kg" class="btn-form" type="button">Kg</button>
<button id="lbs" class="btn-form" type="button">Lbs</button>
Use JavaScript to add an event listener to both unit buttons that call the same function which will update the innerHTML of the unit headings to match the clicked button. When initializing the unit heading elements you should not give them all the same id but rather a common class and you must also append a cloned copy of the element or it will just move the element form one spot to the next:
document.querySelectorAll('#kg, #lbs').forEach(ub => ub.addEventListener('click', units));
function units(e) {
let units = document.querySelectorAll(".value.unit");
if (units.length == 0) {
let newElement = document.createElement("h3");
newElement.setAttribute("class", "value unit");
document.querySelectorAll(".dynamic").forEach((dyn) => {
// append a cloned copy to each, not the same newElement
dyn.appendChild(newElement.cloneNode())
});
// re-run the query to find the newly added nodes
units = document.querySelectorAll(".value.unit");
}
// set the content
units.forEach(unit => unit.innerHTML = e.target.innerHTML);
}

Assign TWO Images to Radio Button

Hi so I have this "product" page (on Fiddle) where I have multiple radio boxes in two classes .choosesize and .choosetea. I want to set up my code where if the 8oz radio button is selected then one set of pictures will appear for all the tea selections and if the 16oz radio button is selected another set of pictures will appear for the tea selections.
I have assigned the small and big images to each tea option but I do not know how to show the small pictures if the small 8oz option is selected.

While you don't have all the "combined" images, I have added a possible solution.
var size = "small"
var teatype = "green"
$('.choosetea input').on('click', function() {
teatype = $(this).attr('data-image');
console.log(size + "_" +teatype)
$('.active').removeClass('active');
$('.columnleft img[data-image = ' + size + "_" +teatype + ']').addClass('active');
$(this).addClass('active');
});
$('.choosesize input').on('click', function() {
size = $(this).attr('data-image');
console.log(size + "_" +teatype)
$('.active').removeClass('active');
$('.columnleft img[data-image = ' + size + "_" +teatype + ']').addClass('active');
$(this).addClass('active');
});
So this will comebine size and teatype, So each image will have the data-image where it should be size_teatype
$(document).ready(function() {
var size = "small"
var teatype = ""
$('.choosetea input').on('click', function() {
teatype = "_"+$(this).attr('data-image');
console.log(size +teatype)
$('.active').removeClass('active');
$('.columnleft img[data-image = ' + size +teatype + ']').addClass('active');
$(this).addClass('active');
});
$('.choosesize input').on('click', function() {
size = $(this).attr('data-image');
console.log(size +teatype)
$('.active').removeClass('active');
$('.columnleft img[data-image = ' + size +teatype + ']').addClass('active');
$(this).addClass('active');
});
//local storage color
//local storage size
// add the value of the added radio boxes in the text box
$('.radios1').change(function(e) {
var selectedValue = parseInt($(this).val());
selectedValue += parseInt($(".radios2").val());
$('#amount').val('$' + selectedValue)
});
//add to cart
});

I also want to make the "DIV WITH CONTROL-BUTTON ID" display as block only if data fetch from API was successful.... Thanks
MY CODE IS BELOW:
"use strict";

Reloading the page using JavaScript is very easy.
You can achieve this by using location.reload()
If you want to achieve reloading using a button, then be sure to add a return false; right after you call location.reload() to prevent bubbling (parents of the button won't know the event occurred).
So, your code will look something like this :
document.getElementById('yourButton').addEventListener('click', function(){
location.reload();
return false;
});
Hope this helps ! :)

Budget doesn't recalculate after deleting last item from data

So I have this code for a budget app that I'm doing on a javascript course on Udemy. There's a function to delete the item from the data structure, from the UI and to update the budget. It works fine until when I delete the last item from the list i.e the last item on the array, it deletes the item from the data array and from the UI, but don't recalculate the budget.
I tried to look up into my code, and didn't found anything, so that's why I need you, more experienced guys help :)

The problem is that you assign to data.totals[type] = sum; inside the forEach loop in calculateTotal(). If there are no items in the array, the loop never runs, so you never do the assignment.
You don't need to do that assignment each time through the loop, just once after the loop is done calculating the total. So it should be
var calculateTotal = function(type) {
var sum = 0;
data.allItems[type].forEach(function(cur) {
sum += cur.value;
})
data.totals[type] = sum;
}

var calculateTotal = function (type) {
var sum = 0;
data.allItems[type].forEach(function (cur) {
sum += cur.value;
data.totals[type] = sum;
}); };
if the data.allItems doesn't have any value then the total not getting updated.
You have to check if the allItems have 0 then update the totals as 0

I saw a problem on html file with the input options:
<option value ="income" selected>+</option>
<option value ="expense">+</option>
You have to use them in your JS code or try setting in the html: value="inc" and value="exp"

Your option values do not match your object properties. You need to change to:
<option value="inc" selected>+</option>
<option value="exp">-</option>
