There's a secret error somewhere in your secret code. You should fix that.
Seriously, how do you expect anyone here to help you fix your code, when you haven't shown us any of your code? 
We can't see your screen. We can't access your computer. We can't read your mind. All we have to work with is what you type in the "message" box. If you can't explain the problem clearly, then we can't help you.
And adding "urgent" and "quick response" to your questions simply tells us that you can't manage your own time. It's not going to force us to answer your unanswerable question any quicker.

Simple. Write code for the drop event and to check if the img tag already has a src attribute.

You should probably work on one DND interface first, and then create 2 more of them and DND each image to a specific DND box. Get the hang of DND first and how it works. It's not as easy as it sounds and DND has some events you have to listen for.
If it ain't broke don't fix it

function isAvgWhole(arr) {
return Number.isInteger(arr.reduce((accum, val) => accum + val) / arr.length)
}
function isAvgBowl(arr)

return Number.isInteger(arr.reduce(function(accum,val)

}
console.log(isAvgWhole([1,1,1,1]))
console.log(isAvgBowl([1,1,1,1]))

Because you're using two completely different calculations:
Method 1:
Sum up all of the items in the array. Divide the sum by the length of the array.
arr.reduce((accum, val) => accum + val) / arr.length
var accum = arr[0];
for (var i = 1; i < arr.length; i++) {
accum = accum + arr[i];
}
var result = accum / arr.length;
Method 2:
For each value in the array, add that value to the accumulator, and divide the intermediate result by the length of the array.
arr.reduce((accum, val) => (accum + val) / arr.length)
var accum = arr[0];
for (var i = 1; i < arr.length; i++) {
accum = accum + arr[i];
accum = accum / arr.length;
}
var result = accum;
Step through both methods with a debugger, or write out the steps on a piece of paper, and it should be obvious why the second method is wrong.

Hey,
I am solving a problem on hackerrank(https://www.hackerrank.com/challenges/compare-the-triplets/problem?h_r=next-challenge&h_v=zen). The problem states to complete the function
compareTriplets which must return an array of two integers, the first being ALice's score and the secoond being Bob's.
compareTriplets has the following parameter(s):
a: an array of integers representing Alice's challenge rating
b: an array of integers representing Bob's challenge rating
For more detail on the problem, refer to the following link:
https://www.hackerrank.com/challenges/compare-the-triplets/problem?h_r=next-challenge&h_v=zen
For the same challenge i wrote the following solution:
function compareTriplets(a, b) {
for (let i = 0; i < 4; i ++) {
points=[];
pointsArray=[];
if (a[i] > b[i]) {
points[i]=1;
pointsArray.push(points[i])
}
if (a[i] === b[i]) {
points[i]=0;
}
if (b[i] > a[i]) {
points[i]=1;
pointsArray.push(points[i])
}
return pointsArray;
}
}
The problem states that the output should be like [1,1] i.e. [points earned by alice, points earned by bob]
But somehow it displays a array with four elements with the values [1], [], [1], []
Refer to https://ibb.co/GCkwM9j for further details.
Can anybody suggest anything?

I would suggest to begin by solving it by hand with a pen and a piece of paper, so that you have a clear knowledge of input and output data as well as required steps. As of now the code you showed does not pass the simplest logic checks: you are provided with triplets (3 values) but operate on array of four values; you have an inconditional return statement inside a loop, rendering this loop kind of useless (it will return at the first iteration); you create two data structures where you only need one; you do not add points to existing values but rather overwrite them.
So, do it by hand first; there is no chance for you to come up with a proper algorithm if you cannot solve it yourself with a pen and paper.

I am looking for a method to close the current tab of the browser window using JavaScript.

Unfortunately you can't for security purposes. You can only close windows that were opened by Javascript.

In earlier times you got the full client path from a file upload and we were running ActiveX on our web pages. What's your point?
|
|
|
|

That is why websites were easily hacked in the earlier times due to inefficient security.
Like I said, javascript can only close windows that was opened by it.

I am making a live subway map, where I have divs representing trains, moving up and down the map.
I had no problem making them move, but I would like them to stop for a few seconds at each station.
Can someone tell me how I can include this in my code?
What line do I need to add, and where?
window.onload = () => {
startSetTimeoutAnimation();
};
function startSetTimeoutAnimation() {
const refreshRate = 1000 / 60;
const maxXPosition = 400;
let rect = document.getElementById('rect0');
let speedX = 0.01;
let positionX = 25;
window.setInterval(() => {
positionX = positionX + speedX;
if (positionX > maxXPosition || positionX < 25) {
speedX = speedX * (-1);
}
rect.style.top = positionX + 'px';
}, refreshRate);
}

images in are loading properly when I am running the application locally but even though images are appearing in the folder on Server but not being loaded in the Sources when I see them, in the same folder structure when ran locally they are being loaded - any help why would that happen? When even the folder contains the images - any help please - thank you.

You should know by now that we cannot guess what your code is doing. Please edit your question and show the proper details of the problem, including the code that is trying to load the images, and the actual path where they are stored.

Yeah I know but here is my problem.
Its an Ember Code and it will be converted into a big app.js file - before that all those files and everything would be converted - I am not sure how can I show you the code -Ember Code before conversion into js or after js conversion. I think Web-pack converts Ember files into js files - I am not very expert in it though. But anyways the Image files are showing up in the folder only thing is they aren't accessible in web page and they are not loading in the resource section when I checked using Chrome Developer tools, and similar scenario, when I use Chrome Dev Tools, Image files are loaded and showing-up in the resources section and it works locally though - any help please
