Increase a number based on Date or Interval javascript (and keep it after refresh page)

I'm struggling for while trying to figure out how to increase a number based on a Date or based on a time (Using setInterval).
I don't know which option is easier. I made it by using setInterval:
HTML
<p class="counter"></p>
JS
let tickets = 35000;
const counter = document.querySelector('.counter');
let interval = setInterval(function(){
console.log(tickets);
if (tickets >= 60000) {
var textSoldOut = `<p>¡Todo vendido!</p>`;
counter.innerHTML = textSoldOut;
console.log("Sold out");
clearInterval(interval);
}else{
var text = `¡${tickets} tickets Sold!`;
contador.innerHTML = text;
console.log(text)
}
const random = Math.floor(Math.random()*(200-100+1)+100);
tickets += random;
}, 10000);
The thing is every time the page is refreshed the counter starts from 35000 again. I am trying to figure out how to storage the var tickets. I guess this would be made by using localStorage, but since I am a beginner in JS, I am not able to do it.
Other option would be by checking the date, and based on that, show a number:
function date() {
var d = new Date();
var month = d.getMonth();
var day = d.getDate();
const counter = document.querySelector('.contador');
const random = Math.floor(Math.random()*(200-100+1)+100);
for (let i = 350000; i <= 60000 ; i++) {
if (month == 0 & day == 28) {
var sum = i + random;
document.getElementById("contador").innerHTML = suma;
}else if (mes == 0 & dia == 30) {
...
} else if (...){
...
}
}
document.getElementById("dia").innerHTML = dia;
document.getElementById("mes").innerHTML = mes;
}
fecha();
Could someone help me out to reach the result?
I would really appreciate it

The Storage object accessible via the localStorage property offers two methods to save or retrieve data: setItem and getItem().
Usage is quite simple. If you want to save the numbers of tickets into a myTickets key on localStorage you have to do it like this:
localStorage.setItem("myTickets", tickets);
To retrieve that data later on:
localStorage.getItem("myTickets");
You just have to make sure to update the myTickets key on localStorage as you increase the number of tickets inside the setinterval callback function.
let tickets = 35000;
if (localStorage.getItem("myTickets") == null) {
localStorage.setItem("myTickets", tickets);
} else {
tickets = localStorage.getItem("myTickets");
}
const counter = document.querySelector('.counter');
let interval = setInterval(function() {
console.log(tickets);
if (tickets >= 60000) {
var textSoldOut = `<p>¡Todo vendido!</p>`;
counter.innerHTML = textSoldOut;
console.log("Sold out");
clearInterval(interval);
} else {
var text = `¡${tickets} tickets Sold!`;
console.log(text)
}
const random = Math.floor(Math.random() * (200 - 100 + 1) + 100);
tickets += random;
localStorage.setItem("myTickets", tickets);
}, 10000);

Adding random number to itself in javascript

I am generating a random number on click in jQuery. At the end of this post, you can see the code that I am working with.
Is there a way where every time a new random number gets generated it gets added to the old one in a variable called totalRandomNumbers?
I want to do it for all three variables random, random_0, random_1.
$("#reset").click(function(){
var random = Math.floor(Math.random() * 12);
var random_0 = Math.floor(Math.random() * 12);
var random_1 = Math.floor(Math.random() * 12);
$("#push0").html(random);
$("#push1").html(random_0);
$("#push2").html(random_1);
$('input[name="hamPush"]').val($("#push0").html());
$('input[name="zikPush"]').val($("#push1").html());
$('input[name="musPush"]').val($("#push2").html());
})

At the start of your JavaScript, make a variable:
var totalRandomNumbers = 0;
And when you generate your random number, add it to the variable.
totalRandomNumbers += (code to generate random number)

var randomSum = 0;
function getRandomInt(min, max) {
min = Math.ceil(min);
max = Math.floor(max);
return Math.floor(Math.random() * (max - min)) + min;
};
function sumRandom() {
randomSum += getRandomInt(1, 100)
};
$('.genRandomButton').on('click', function() {
console.log(randomSum)
}

Just tried in browser console:
var _totalRandomNumbers = 0;
Object.defineProperty(window, "totalRandomNumbers", {
get: function() { return _totalRandomNumbers += Math.random(); }
});
console.log(totalRandomNumbers);
console.log(totalRandomNumbers);
and so on :-)
You can do anything in get accessor, store old values etc.

JavaScript - Random numbers and variables between functions

I am new to JavaScript, I have two roll functions for each roll of a frame. I am unable to get the values of each of those rolls into a frame function to call on and use. If someone could help this would be great! thanks in advance, My code is below.
var Bowling = function() {
var STARTING_TOTAL = 0;
ROLL_ONE = Math.floor(Math.random() * 11);
ROLL_TWO = Math.floor(Math.random() * 11);
this.score = STARTING_TOTAL;
var firstScore;
var secondScore;
var totalScore;
Bowling.prototype.firstRoll = function() {
firstScore = ROLL_ONE
return firstScore;
};
Bowling.prototype.secondRoll = function() {
secondScore = Math.floor(Math.random() * 11 - firstScore);
return secondScore;
};
Bowling.prototype.frameScore = function () {
totalScore = firstScore + secondScore
return totalScore;
};
};

I can only guess what you're trying to achieve. I refactored you code a little bit:
var Bowling = function () {
var STARTING_TOTAL = 0;
this.score = STARTING_TOTAL; // remains unused; did you mean "totalScore"?
this.firstScore = 0;
this.secondScore = 0;
};
Bowling.prototype.firstRoll = function () {
this.firstScore = Math.floor(Math.random() * 11);
return this.firstScore;
};
Bowling.prototype.secondRoll = function () {
this.secondScore = Math.floor(Math.random() * 11 - this.firstScore);
return this.secondScore;
};
Bowling.prototype.frameScore = function () {
this.totalScore = this.firstScore + this.secondScore
return this.totalScore;
};
// now use it like this:
var bowling = new Bowling();
console.log(bowling.firstRoll());
console.log(bowling.secondRoll());
console.log(bowling.frameScore());
In my approach however, firstScore and secondScore are public properties.

To address the question of why the second roll can be negative: as your code currently stands, if the second roll is smaller than the first roll, the result will be negative. If you want it so that if the first roll is 6, the second roll will be a number between 0 and 4, try something like:
function randomInt(maxNum) {
return Math.floor(Math.random() * maxNum)
}
var maxRoll = 11
var rollOne = randomInt(maxRoll)
var rollTwo = randomInt(maxRoll - rollOne)
console.log(rollOne)
console.log(rollTwo)
Press "Run Code Snippet" over and over again to see it work.
Changes I've made:
I made a function, randomInt that gives a random number from 0 to some max number. This saves you from needing to write the same code twice.
I created a variable maxRoll that keeps track of what the highest possible roll is.
I subtract maxRoll from the first roll to determine what the max number for the second roll should be (maxRoll - rollOne). That's then given to randomInt.

Random number game refresh Javascript

I have a "guess a random number" game, where my code generates a random number between 1 and 100, and you try and guess the number. I'd like to have a reset button that refreshes the game by changing the variable with the random number in it. This is the relevant code I have.
var comparedNumber = RandomNumber();
function RandomNumber(){
var randomNumber = Math.floor(Math.random() * 100) + 1;
return randomNumber;
};
refresh.onclick = function(){
genComparedNumber();
};
Function Random Number runs on page load, but I can't seem to get comparedNumber to change.

Same logic as #juvian's answer
var Game = {
comparedNumber : randomNumber(),
refreshNumber : function(){
this.comparedNumber = randomNumber();
alert(this.comparedNumber);
},
refreshButton : document.querySelector("#refresh-button")
}
function randomNumber(){
var randomNumber = Math.floor(Math.random() * 100) + 1;
return randomNumber;
}
Game.refreshButton.addEventListener("click",Game.refreshNumber,false);
<button id="refresh-button">Refresh</button>

Make number grow with jQuery using same amount of time for every number

My goal is to perform a jQuery script that'll make any number visually grow from zero until its value with setInterval().
Here's what I came up with:
$('.grow').each(function() {
var $el = $(this);
var max = parseInt($el.text().replace(/\s/g, ''));
var refresh = 5;
var start = 0;
var step = 1;
var interval = window.setInterval(function() {
start += step;
$el.text(start);
if(start >= max)
clearInterval(interval);
}, refresh);
});
My problem is I have numbers ranging from a few hundreds to several hundreds thousands. With this script, bigger number take more time to reach their value.
My goal is to make any number, regardless of its goal value, take the same amount of time to reach it. I sense that I should divide the number by the number of seconds I want the animation to run and then, set the result as the interval step?
I'm inquiring but still seeking for help :)
Thanks.

$('.grow').each(function() {
var $el = $(this);
var max = parseInt($el.text().replace(/\s/g, ''));
var duration = 1000; // shared duration of all elements' animation
var refresh = 5;
var frames = duration / refresh; // number of frames (steps)
var start = 0;
var step = Math.max(Math.round(max / frames), 1); // step should be >= 1
var interval = window.setInterval(function() {
if(start + step < max) {
start += step;
}
else {
start = max;
clearInterval(interval);
}
$el.text(start);
}, refresh);
});

This should work I suppose,
$('.grow').each(function() {
var $el = $(this);
var max = parseInt($el.text().replace(/\s/g, ''));
var start = 0;
var refresh = 5;
var totalSteps = 10;
var step = max/totalSteps;
function calculate(){
start += step;
$el.text(Math.round(start));
if(start < max){
setTimeout(function() {
calculate();
}, refresh);
}
}
calculate();
});
This will always finish in 100 steps. I.e. 100*refresh = 100*5 = 500 seconds.
