Try to create rain fall in JS

I learn javascript and i try to create a rain falling in js but have a problem. After many tries i code something like this. First version of my app can simulate to rain for only one rain drop and now i'd like to translate it to many of rain drops
function Raining() {
setInterval(Raining, 40)
if (yPosition < 1000) {
yPosition += step
} else {
yPosition = 0
rain.style.top = 0
}
}
//Rain
let xPosition;
let yPosition = 0;
const step = .5
//Making water
for (i = 0; i < 20; i++) {
const el = document.createElement('div')
document.querySelector('body').appendChild(el)
//Random x location
let randomXPosition = Math.trunc(Math.random() * 100 + 1)
el.style.left = `${randomXPosition}%`
}
let rain = document.querySelectorAll('div')
for (i = 0; i < rain.length; i++) {
rain[i].style.top = `${yPosition}px`
Raining()
}
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
body {
overflow: hidden;
height: 100vh;
}
div {
position: absolute;
top: 0;
left: 50%;
background-color: royalblue;
width: 3px;
height: 20px;
}
<div class="rain"></div>
Code execute only once . I know that here is a lot of mistakes but please help what's wrong here.

You have more than one rain
This works better but you really ned a random step for each drop
function Raining() {
yPosition += step;
for (i = 0; i < rain.length; i++) {
yPosition += Math.floor(Math.random()*i)
rain[i].style.top = `${yPosition}px`
}
if (yPosition > 1000) {
yPosition = 0
}
}
//Rain
let xPosition;
let yPosition = 0;
const step = .5
//Making water
for (i = 0; i < 20; i++) {
const el = document.createElement('div')
document.querySelector('body').appendChild(el)
//Random x location
let randomXPosition = Math.trunc(Math.random() * 100 + 1)
el.style.left = `${randomXPosition}%`
}
let rain = document.querySelectorAll('div')
setInterval(Raining, 300)
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
body {
overflow: hidden;
height: 100vh;
}
div {
position: absolute;
top: 0;
left: 50%;
background-color: royalblue;
width: 3px;
height: 20px;
}
<div class="rain"></div>

Opposing condition for a div

I need to make a ball grow until it reaches 400, which thereafter it would shrink the same way. Would really appreciate feedback what I'm doing wrong in my code:
var
ball1Size = 100
, ball2Size = 100
, ball2SizeStep = 50
;
function onBall2Click()
{
var ball2 = document.querySelector('.ball2');
ball2Size = ball2Size + 50;
if (ball2Size > 400) {
ball2Size = ball2Size - 100;
}
else {
ball2Size - 150;
}
ball2.innerText = ball2Size;
ball2.style.width = ball2Size;
ball2.style.height = ball2Size;
}
body {
background-color : black;
text-align : center;
}
h1 {
color : white;
}
div {
width : 100px;
height : 100px;
margin : auto;
margin-bottom : 10px;
border-radius : 50%;
transition : 0.3s;
line-height : 50px;
}
.ball2 {
background-color : orange;
}
<div class="ball2" onclick="onBall2Click()">
SIZE
</div>

See code fix and syntax fixes
here:
var ball1Size = 100;
var ball2Size = 100;
var ball2SizeStep = 50;
function onBall2Click() {
var ball2 = document.querySelector('.ball2');
ball2Size = ball2Size + ball2SizeStep;
if (ball2Size >= 400) {
ball2SizeStep = -50
} else if (ball2Size <= 50) {
ball2SizeStep = 50
}
ball2.innerText = ball2Size;
ball2.style.width = ball2Size + "px";
ball2.style.height = ball2Size + "px";
}
body {
background-color: black;
text-align: center;
}
h1 {
color: white;
}
div {
width: 100px;
height: 100px;
margin: auto;
margin-bottom: 10px;
border-radius: 50%;
transition: 0.3s;
line-height: 50px;
}
.ball2 {
background-color: orange;
}
<div class="ball2" onclick="onBall2Click()" >
SIZE
</div>

This is what you want to do, increase the balls size for each click that it can be increased for, i.e., is under 400, when it reaches 400, decrease the ball size for each click until it reaches its original size. Rinse and repeat.
var ball1Size = 100;
var ball2Size = 100;
var ball2SizeStep = 50;
let isBallDecreasing = false;
function onBall2Click() {
var ball2 = document.querySelector('.ball2');
if (ball2Size === 100) isBallDecreasing = false;
if (ball2Size >= 400 || isBallDecreasing) {
ball2Size -= 50;
isBallDecreasing = true;
} else {
ball2Size += 50
isBallDecreasing = false;
}
ball2.innerText = ball2Size;
ball2.style.width = ball2Size;
ball2.style.height = ball2Size
}
<div class="ball2" onclick="onBall2Click()">
SIZE
</div>

Using a boolean to track the direction can simplify it
let direction = 1;
const min = 100;
const max = 400;
const step = 50;
let current = 100;
var ball = document.querySelector(".ball2");
ball.addEventListener("click", function() {
current += direction * step;
if (current >= max) {
current = max;
direction = -1;
} else if (current <= min) {
current = min;
direction = 1;
}
updateElem();
});
function updateElem() {
ball.textContent = current;
ball.style.width = current + 'px';
ball.style.height = current + 'px';
}
updateElem();
body {
background-color: black;
text-align: center;
}
h1 {
color: white;
}
.ball {
width: 100px;
height: 100px;
margin: auto;
margin-bottom: 10px;
border-radius: 50%;
transition: 0.3s;
line-height: 50px;
}
.ball2 {
background-color: orange;
}
<div class="ball ball2">
SIZE
</div>
If you are going to have more than one of these you probably want to have some sort of way to keep track. Using data attributes can help out so you do not need more than one copy of the code.
document.querySelectorAll(".ball2").forEach(function (ball) {
ball.addEventListener("click", function () {
let direction = +ball.dataset.direction;
const min = +ball.dataset.min;
const max = +ball.dataset.max;
const step = +ball.dataset.step;
const current = +ball.dataset.current;
let updated = current + direction * step;
if (updated >= max) {
updated = max;
direction = -1;
} else if (updated <=min) {
updated = min;
direction = 1;
}
updateElem();
ball.dataset.direction = direction;
ball.dataset.current = updated;
});
function updateElem() {
const num = ball.dataset.current;
ball.textContent = num;
ball.style.width = num + 'px';
ball.style.height = num + 'px';
}
updateElem();
});
body {
background-color: black;
text-align: center;
}
h1 {
color: white;
}
.ball {
width: 100px;
height: 100px;
margin: auto;
margin-bottom: 10px;
border-radius: 50%;
transition: 0.3s;
line-height: 50px;
}
.ball2 {
background-color: orange;
}
<div
class="ball ball2"
data-direction="1"
data-min="100"
data-max="400"
data-step="50"
data-current="100">
SIZE
</div>
<div
class="ball ball2"
data-direction="-1"
data-min="100"
data-max="400"
data-step="50"
data-current="400">
SIZE
</div>
<div
class="ball ball2"
data-direction="1"
data-min="0"
data-max="1000"
data-step="100"
data-current="200">
SIZE
</div>

you can also Use CSS custom properties for simplifying your code:
const ball2 = document.querySelector('.ball2');
var
ballSz = 100
, ball2SizeStep = 50
;
ball2.onclick =()=>
{
ballSz += ball2SizeStep
ball2.textContent = ballSz
ball2.style.setProperty('--szHW', ballSz + 'px')
if (ballSz >= 400) ball2SizeStep = -50
if (ballSz <= 100) ball2SizeStep = +50
}
body {
background-color : black;
text-align : center;
}
h1 {
color : white;
}
div {
--szHW : 100px; /* <--- CSS custom properties */
width : var(--szHW);
height : var(--szHW);
margin : auto;
margin-bottom : 10px;
border-radius : 50%;
transition : 0.3s;
line-height : 50px;
}
.ball2 {
background-color : orange;
}
<div class="ball2">
SIZE
</div>
the same, for multiples balls
document.querySelectorAll('.ball2').forEach( ball2 =>
{
ball2.style.setProperty('--szHW', ball2.dataset.size + 'px') // init sizes according to data-size value
ball2.onclick =_=>
{
let
min = Number(ball2.dataset.min)
, max = Number(ball2.dataset.max)
, step = Number(ball2.dataset.step)
, size = Number(ball2.dataset.size)
;
if ( size === min && step < 0
|| size === max && step > 0 )
{
step *= -1
ball2.dataset.step = step
}
ball2.dataset.size = size += step
ball2.style.setProperty('--szHW', size + 'px')
}
})
body {
background-color : black;
text-align : center;
}
div.ball2 {
--szHW : 100px; /* <--- CSS custom properties */
width : var(--szHW);
height : var(--szHW);
margin : auto;
margin-bottom : 10px;
border-radius : 50%;
transition : 0.3s;
line-height : 50px;
background : orange;
}
div.ball2::before {
content: attr(data-size)
}
<div class="ball2" data-min="100" data-max="400" data-step="50" data-size="100"></div>
<div class="ball2" data-min="100" data-max="400" data-step="50" data-size="400"></div>
<div class="ball2" data-min="100" data-max="1000" data-step="100" data-size="200"></div>

Need help to limit how many tiles and target spawn in this game

I got some simple bomberman game from code pen.For my study,i need to limit how many tiles and target.For tiles max 32 and target 7 (tiles grey & target red).
Here the source : codepen.io/Digiben/pen/oGYGrx
I dont understand how the script create the target and tiles with random algoritm.
Thanks for anyone who look this thread.

I'm not certain I understand your question, but I think you're trying to debug the createTargets method in the Targets class. The problem there is an extra closing bracket (}) right before the line with //Show Total Targets.

Can not get value inside loop using pure JavaScript

Why I cannot get value inside the loop
Can use javascript only
Pause text for 2000ms on hover
reverse work on hover but should pause it first and then reverse the sequence until mouse out.
loop on reading text from textarea "input"
find this line in javascript to control delay
if(document.getElementById('flag2').value == "0"){

2 - 4 : center 2

Oh, hey there, TIDWRTWHUFOO fans. Thinking about going for a little dip this summer? How about you go for a swim with a one-ton crab that will smash you under its massive legs? Sound fun? Definitely!
Crabster is a wild crab-like robot designed to explore the deepest oceans without smashing itself into a squashed tin can. It has massive legs, a large body, and lots of cameras so it can find you even if you’re the dude from The Big Blue and can dive really deep. There’s no escaping our future robotic-aquatic overlords

Responsive jQuery sketch application failing when div size is < 7px

I'm trying to build a responsive sketch application with jQuery. It works, except for when the size for the divs within the .box class become less than 7px. I tried to make a fiddle but I couldn't see any output. I'll just leave the code here and hope for the best!
var wide = 150;
$(document).ready(function() {
makeGrid(wide);
$('body').on('mousedown mouseup', function mouseState(e) {
if (e.type == "mousedown") {
$(".box").mouseenter(function() {
$(this).css("background-color", "black");
});
} else {
$(".box").unbind('mouseenter mouseleave');
}
});
});
var makeGrid = function(wide) {
var boxSide = calculateBoxSide(wide);
var boxRowNumber = calculateRowNumbers(boxSide);
var boxSideLength = boxSide + "px";
$("body").css("line-height", boxSideLength);
for (i = 0; i < wide; i++) {
for (j = 0; j < boxRowNumber; j++) {
$box = $('<div class="box">').appendTo(".sketchpad")
$box.css("width", boxSideLength);
$box.css("height", boxSideLength);
}
}
}
var calculateBoxSide = function(wide) {
return $(".sketchpad").width() / wide;
}
var calculateRowNumbers = function(boxSideLength) {
return Math.round($(".sketchpad").height() / boxSideLength);
}
.sketchpad {
margin: 0 auto;
width: 50%;
height: 500px;
text-align: center;
}
.box {
display: inline-block;
background-color: grey;
vertical-align: top;
}
.box:hover {
background-color: black;
}
