Having trouble reducing the total in this small todo app

I am having a hard time trying to figure out how to get the the value from every new Li and reduce it (add) to then output to my h2. Can't figure out what I am doing wrong. Any help would be greatly appreciated! Codepen: https://codepen.io/Chasehud26/pen/Poagjwy
I tried to console.log different variables to see if there were any hints of what is going wrong.
const form = document.querySelector("form")
const nameInput = document.querySelector("#name-input")
const priceInput = document.querySelector("#price-input")
const button = document.querySelector("button")
const nameUl = document.querySelector("#item-name")
const priceUl = document.querySelector("#item-price")
const h2 = document.querySelector("h2")
const nameLi = document.createElement("li")
const priceLi = document.createElement("li")
form.addEventListener("submit", function (e) {
e.preventDefault()
let nameVal = nameInput.value
let priceVal = priceInput.value
const nameLi = document.createElement("li")
const priceLi = document.createElement("li")
nameUl.appendChild(nameLi)
nameLi.innerHTML = nameInput.value
priceUl.appendChild(priceLi)
priceLi.textContent = `${priceInput.value}`
showTotals()
})
//TRYING TO ADD TOGETHER ALL THE PRICE VALUES AND THEN PUT IT TO MY H2//
function showTotals() {
const priceList = document.querySelectorAll("li")
for (let priceLists of priceList) {
const total = []
total.push(parseFloat(priceLists.textContent));
const totalMoney = total.reduce(function (total, item) {
total += item;
return total;
}, 0);
const finalMoney = totalMoney.toFixed(2);
h2.textContent = finalMoney;
}
}

You need to have your const total [] array initialized outside of the for loop. also, when you setup your <li> decorators, you need to differentiate between the number and non-number fields, since the way you had it, it was trying to add the text 'li' fields also:
/// truncated for clarity
const nameLi = document.createElement("li")
const priceLi = document.createElement("li")
priceLi.classList.add('num') // <== this line added
//// =================
function showTotals() {
const priceList = document.querySelectorAll("li.num") // added class
const total = [] // <== move this to here
for (let priceLists of priceList) {
total.push(parseFloat(priceLists.textContent));
const totalMoney = total.reduce(function (total, item) {
total += item;
return total;
}, 0);
const finalMoney = totalMoney.toFixed(2);
h2.textContent = finalMoney;
}

How do I display every element from my localStorage item?

i'm trying to create a simple To-do list, and my question is how do i get all elements of a single item in localStorage displayed?
pushing things into localStorage in a form of an array works fine, but only thing I see on my page is the first index of the "tasks" array.
const inputEl = document.getElementById("inputEl")
const submitBtn = document.getElementById("submit")
const clearBtn = document.getElementById("clearBtn")
const todoListContainer = document.getElementById("todoList")
const taskContainer = document.querySelector(".task")
const cancelBtn = document.querySelector(".cancelBtn")
const doneBtn = document.querySelector(".doneBtn")
const errorMsg = document.querySelector(".error")
let localStorageContent = localStorage.getItem("tasks")
let tasks = []
function createTask(){
if(inputEl.value.length != 0){
const newDiv = document.createElement("div")
newDiv.classList.add("task")
const newParagraph = document.createElement("p")
const newCancelBtn = document.createElement("button")
newCancelBtn.classList.add("cancelBtn")
newCancelBtn.textContent = "X"
const newDoneBtn = document.createElement("button")
newDoneBtn.classList.add("doneBtn")
newDoneBtn.textContent = "Done"
todoListContainer.appendChild(newDiv)
newDiv.appendChild(newParagraph)
newDiv.appendChild(newCancelBtn)
newDiv.appendChild(newDoneBtn)
//^^ Creating a container for a new task, with all its elements and assigning the classes^^
tasks.push(inputEl.value)
localStorage.setItem("tasks", JSON.stringify(tasks))
inputEl.value = ""
newParagraph.textContent = JSON.parse(localStorageContent)
errorMsg.textContent = ""
}else{
errorMsg.textContent = "You have to type something in!"
errorMsg.classList.toggle("visibility")
}
}
submitBtn.addEventListener("click", () =>{
createTask()
})

When you execute JSON.parse(localStorageContent) you convert your string into an array, that's right.
But:
newParagraph.textContent = JSON.parse(localStorageContent)
is the same as:
newParagraph.textContent = JSON.parse(localStorageContent)[0]
So, you have to loop through your JSON.parse(localStorageContent)
array... Therefore, create a new variable:
let tasksItem = JSON.parse(localStorageContent)
and loop on with .forEach method

Incorrect loading order from local storage

I'm having problem with loading from local storage.
Here's a part of the code
const getTerminus = () => {
let terminus;
if (localStorage.getItem("terminus") === null) {
terminus = [];
} else {
terminus = JSON.parse(localStorage.getItem("terminus"));
}
let directions;
if (localStorage.getItem("directions") === null) {
directions = [];
} else {
directions = JSON.parse(localStorage.getItem("directions"));
}
terminus.forEach(async(stop) => {
let API_URL =
"https://ckan.multimediagdansk.pl/dataset/c24aa637-3619-4dc2-a171-a23eec8f2172/resource/d3e96eb6-25ad-4d6c-8651-b1eb39155945/download/stopsingdansk.json";
let response = await fetch(API_URL);
let data = await response.json();
const {
stops,
stopId,
stopName,
stopCode,
zoneId
} = data;
let input = stop;
let ID;
let dataArr = [];
for (let i = 0; i < stops.length; i++) {
if (
stops[i].stopName === input &&
stops[i].stopCode === directions[terminus.indexOf(input)] &&
stops[i].zoneId === 1
) {
ID = stops[i].stopId;
dataArr = [ID, stops[i].stopName];
}
}
API_URL = `https://ckan2.multimediagdansk.pl/delays?stopId=${ID}`;
response = await fetch(API_URL);
data = await response.json();
const {
delay,
estimatedTime,
routeId,
headsign
} = data;
let times = [];
let routeIds = [];
let headsigns = [];
for (let i = 0; i < delay.length; i++) {
times.push(delay[i].estimatedTime);
routeIds.push(delay[i].routeId);
headsigns.push(delay[i].headsign);
}
routeIds.push(" ");
times.push(" ");
const cardDiv = document.createElement("div");
cardDiv.classList.add("card");
const stopNameDiv = document.createElement("div");
stopNameDiv.classList.add("stop-name-div");
cardDiv.appendChild(stopNameDiv);
const stopNameSpan = document.createElement("span");
stopNameSpan.innerText = dataArr[1];
stopNameSpan.classList.add("stop-name-span");
stopNameDiv.appendChild(stopNameSpan);
const scheduleDiv = document.createElement("div");
scheduleDiv.classList.add("schedule-div");
cardDiv.appendChild(scheduleDiv);
if (headsigns.length !== 0) {
routeIds.unshift("Line");
headsigns.unshift("Direction");
times.unshift("Departure");
}
const lineSpan = document.createElement("span");
lineSpan.innerText = routeIds.join("\n");
lineSpan.classList.add("line-span");
scheduleDiv.appendChild(lineSpan);
const dirSpan = document.createElement("span");
dirSpan.innerText = headsigns.join("\n");
dirSpan.classList.add("dir-span");
scheduleDiv.appendChild(dirSpan);
const timeSpan = document.createElement("span");
timeSpan.innerText = times.join("\n");
timeSpan.classList.add("time-span");
scheduleDiv.appendChild(timeSpan);
const buttonsDiv = document.createElement("div");
buttonsDiv.classList.add("buttons-div");
cardDiv.appendChild(buttonsDiv);
const deleteButton = document.createElement("button");
deleteButton.innerHTML = '<i class="fas fa-trash"></i>';
deleteButton.classList.add("delete-button");
buttonsDiv.appendChild(deleteButton);
const dirButton = document.createElement("button");
dirButton.innerHTML = '<i class="fas fa-retweet"></i>';
dirButton.classList.add("reverse-button");
buttonsDiv.appendChild(dirButton);
stopList.appendChild(cardDiv);
});
};
document.addEventListener("DOMContentLoaded", getTerminus);
Terminus contains stop names, and directions contains direction codes.
On refresh, it fetches data from API based on stop name and direction, and displays a card with departure time etc.
The problem is, on closing and re-opening the page cards are sometimes displayed in a wrong order. I have found out, that as time between closing and opening lengthens, the probability of this occurring gets higher. After simple refresh everything is in correct order.
Does it have something to do with browser cache? Has anyone had similar issue or knows what's going on?

Alright, as #Yoshi stated, it was insequential promise error. I managed to fix it by using reduce().
Here are the threads that helped me

Javascript - can't iterate over object in incremental search

I'm very new to javascript/dev so I hope there is a an obvious solution that I've not thought of. My code returns search items from TVMaze.com API. The feature giving me trouble is the incremental search (as a user types in input box, the code returns and displays images by creating a new div and appending images, removing and replacing the an div).
My problem is that on deleting all characters from input box, I receive the error: "Uncaught (in promise) TypeError: shows is not iterable" which I suppose means that there is no object to iterate over? Thanks in advance for any help.
const input = document.querySelector("#query");
input.addEventListener("input", async function (e) {
e.preventDefault();
const searchTerm = e.target.value;
const config = { params: { q: searchTerm } };
const res = await axios.get(`http://api.tvmaze.com/search/shows?`, config);
makeImages(res.data);
clearList();
});
const makeImages = (shows) => {
const div = document.createElement("div");
for (let result of shows) {
if (result.show.image) {
const img = document.createElement("IMG");
img.className += "resultImage";
img.src = result.show.image.medium;
const title = document.createElement("h3");
title.className += "resultTitle";
title.innerText = result.show.name;
const year = document.createElement("h4");
year.className += "score";
year.innerText = result.show.premiered;
var sub = year.innerText.substring(0, 4);
var yearNum = parseInt(sub);
div.append(year);
div.append(img);
div.append(title);
document.body.appendChild(div);
}
if (yearNum <= 2000) {
var retro = document.createElement("h5");
retro.className = "retro";
retro.innerText = "retro";
div.append(retro);
}
}
};
let clearList = () => {
var allImg = document.querySelectorAll("IMG");
if (allImg.length === 0) {
document.createElement("div");
return makeImages();
}
var oldDiv = document.querySelector("div");
oldDiv.remove();
console.log(oldDiv);
};

How do I create an edit function inside of a list?

Currently I have a delete function already which is shown by a cross
So how I am doing this is by using a function that renders in the information from another database, into this list.
function renderCafe(doc){
let li = document.createElement('li');
let name = document.createElement('span');
let city = document.createElement('span');
let cross = document.createElement('div');
li.setAttribute('data-id', doc.id);
name.textContent = doc.data().name;
city.textContent = doc.data().city;
cross.textContent = 'x';
li.appendChild(name);
li.appendChild(city);
li.appendChild(cross);
cafeList.appendChild(li);
// deleting data
cross.addEventListener('click', (e) => {
e.stopPropagation();
let id = e.target.parentElement.getAttribute('data-id');
db.collection('cafes').doc(id).delete();
});}
So how do I create the edit button function like this delete one? Should it also be an EventListener that occurs when clicked?
I was thinking to have an edit button, when clicked, changes into "Update", while the static information turns into a text box with the current values.
Then when the "Update" is being clicked, it then saves the information.
I am a student, and have no prior knowledge in javascript, i took these codes from tutorials that I can find online.

Here's a possible solution, similar to your style.
Replace the alert with a database update.
Make sure you're listening for document changes, and updating your UI accordingly, so that the new name and city will replace your old ones.
const cafeList = document.getElementById('cafe-list');
const sampleCafes = [
{ data: () => ({ name: 'new cafe', city: 'new city'}), id: 'sample-cafe' },
];
sampleCafes.forEach(cafe => renderCafe(cafe));
function renderCafe(doc){
let li = document.createElement('li');
let name = document.createElement('p');
let city = document.createElement('p');
let nameInput = document.createElement('input');
let cityInput = document.createElement('input');
let edit = document.createElement('div');
let submit = document.createElement('div');
let cross = document.createElement('div');
li.setAttribute('data-id', doc.id);
name.textContent = doc.data().name;
city.textContent = doc.data().city;
nameInput.value = name.textContent;
cityInput.value = city.textContent;
nameInput.hidden = true;
cityInput.hidden = true;
edit.textContent = 'edit';
submit.textContent = 'submit';
submit.hidden = true;
cross.textContent = 'x';
li.appendChild(name);
li.appendChild(city);
li.appendChild(nameInput);
li.appendChild(cityInput);
li.appendChild(edit);
li.appendChild(submit);
li.appendChild(cross);
cafeList.appendChild(li);
// deleting data
cross.addEventListener('click', (e) => {
e.stopPropagation();
let id = e.target.parentElement.getAttribute('data-id');
alert(`db.collection('cafes').doc(id).delete();`);
});
// editing data
edit.addEventListener('click', (e) => {
e.stopPropagation();
nameInput.hidden = false;
cityInput.hidden = false;
submit.hidden = false;
name.hidden = true;
city.hidden = true;
edit.hidden = true;
});
// submitting new data
submit.addEventListener('click', (e) => {
e.stopPropagation();
const id = e.target.parentElement.getAttribute('data-id');
nameInput.hidden = true;
cityInput.hidden = true;
submit.hidden = true;
name.hidden = false;
city.hidden = false;
edit.hidden = false;
const newName = nameInput.value;
const newCity = cityInput.value;
alert(`TODO: update doc '${id}' to\n{name: '${newName}', city: '${newCity}'}.`);
});
}
