If I have a list of arrays as follows, what would be the quickest way to check if today i.e. 2022-03-08T23:30:00.000Z is within 5 days of any of the future dates and return true along with the nearest future date (within a 5 day window)?
For example, in this example, it would return 2022-03-13T13:00:00.000Z as the nearest future date and return as true because it falls under this date.

How to modify a formula to include another element input inside my code?

On my pricing page, I've got a pricing estimator; input an order value and a return rate (%) and price estimate will print into a div block below. The formula should look like this: ((orderValue * 0.05, 2) + 4) + ((returnRate / 100) * 4)... Can anyone see why this isn't working?
var elDeliveryPrice = document.getElementById('deliveryPrice');
var elOrderValue = document.getElementById('orderValue');
var elReturnRate = document.getElementById('returnRate');
var formatter = new Intl.NumberFormat('gb-GB', { style: 'currency', currency: 'GBP' });
elOrderValue.addEventListener('keyup', _ => {
let curVal = elOrderValue.value;
let curValFloat = parseFloat(curVal);
if (isNaN(curValFloat)) {
elDeliveryPrice.innerHTML = '';
return;
}
elDeliveryPrice.innerHTML = formatter.format(Math.max(curValFloat * 0.05,2) + 4) + (parseInt("elReturnRate") / 100)) * 4;
});

There are a few things that cause your issues. For starters you should also listen to 'keyup' on the returnRate input box. Secondly you should handle NaN of the returnRate value.
For example:
var elDeliveryPrice = document.getElementById('deliveryPrice');
var elOrderValue = document.getElementById('orderValue');
var elReturnRate = document.getElementById('returnRate');
var formatter = new Intl.NumberFormat('gb-GB', { style: 'currency', currency: 'GBP' });
function calc() {
let curVal = elOrderValue.value;
let curValFloat = parseFloat(curVal);
let curRate = parseFloat(elReturnRate.value);
if (isNaN(curValFloat) || isNaN(curRate)) {
elDeliveryPrice.innerHTML = '£ _';
return;
}
elDeliveryPrice.innerHTML = formatter.format(Math.max(curValFloat * 0.05,2) + 4 + (curRate / 100) * 4);
}
elOrderValue.addEventListener('keyup', calc);
elReturnRate.addEventListener('keyup', calc);

You can divide a percent number by 100 to get the correct number to include in your calculation. If the return rate input is given in text, you can convert to a number using parseInt(returnRate) e.g.
Math.max(curValFloat * 0.05,2) + 4 + (parseInt(returnRate) / 100) * 4

I have the next code in javascript:
var exponential = 2.71828182845904523536028747135266249775724709369995957496696762772407663035354759457138217852516642742746;
var numerator, denominator;
function fact(x) {
if(x==0) {
return 1;
}
return x * fact(x-1);
}
function poisson(k, landa) {
exponentialPower = Math.pow(exponential, -landa); // negative power k
landaPowerK = Math.pow(landa, k); // Landa elevated k
numerator = exponentialPower * landaPowerK;
denominator = fact(k); // factorial of k.
return (numerator / denominator);
}
I need parse to php but i don't know how...
Can somebody help me?

you should put below variables within poisson function also dont think you need to initialize $numerator and $dominator to 0;
$exponential = 2;
$numerator = 0;
$dominator = 0;
function fact($x) {
if($x==0) {
return 1;
}
return $x * fact($x-1);
}
function poisson($k, $landa)
{
$exponential = 2;
$exponentialPower = pow($exponential, -$landa);
$landaPowerK = pow($landa,$k);
$numerator = $exponentialPower * $landaPowerK;
$dominator = fact($k);
echo ($numerator / $dominator);
}
poisson(1,2);

I am trying to make some calculations between inputs , I have 7 inputs and what I want to do is making calculations between them , so this is my code
$('.empCosts').on('input', function () {
var perHour = parseInt($('#per_hour').val());
var hours = parseInt($('#hour').val());
var perDay = parseInt($('#per_day').val());
var days = parseInt($('#day').val());
var perMonth = parseInt($('#per_month').val());
var month = parseInt($('#months').val());
var perYear = parseInt($('#per_year').val());
var perdayVal = parseInt(perHour * hours);
var perMonthVal = parseInt(perDay * days);
var perYearVal = parseInt(perMonth * month);
var perHourVal = parseInt(perDay / hours);
var perMonthDivide = parseInt(perYearVal / month);
$("#per_day").val(perdayVal);
$("#per_month").val(perMonthVal);
$("#per_year").val(perYearVal);
$("#per_hour").val(perHourVal);
if($(this).is(":focus")){
alert('sdfasdfad');
}
});
these inputs should be connected either you multiply or divide , when I try to change per_day value it doesn't change because I already set the value of that input with var perdayVal = parseInt(perHour * hours);, I want either you increase the number or decrease it , it should make the calculation either multiplying or dividing the inputs, here you have the fiddle
DEMO

try this https://jsfiddle.net/2jb2e3Lv/7/
$('.empCosts').on('input', function () {
var perHour = parseInt($('#per_hour').val());
var hours = parseInt($('#hour').val());
var perDay = parseInt($('#per_day').val());
var days = parseInt($('#day').val());
var perMonth = parseInt($('#per_month').val());
var month = parseInt($('#months').val());
var perYear = parseInt($('#per_year').val());
var perdayVal = perHour * hours;
var perMonthVal = perDay * days;
var perYearVal = perMonth * month;
$(this).attr("id") !== "per_day" && $("#per_day").val(perdayVal);
$(this).attr("id") !== "per_month" && $("#per_month").val(perMonthVal);
$(this).attr("id") !== "per_year" && $("#per_year").val(perYearVal);

So I am creating a web app and I get some data.
There are points you have now (now=284), and total points (total=1000). So, The difference between them is dif=716.
How do I use javascript to turn the difference into a percentage value, for example, 32% or whatever?
Thanks

This is a math question, not programming, but you ask for javascript here you are an example:
var value = 249;
var total = 1000;
var calcPercent = function(v, t) {
return 100*v/t;
};
alert(calcPercent(value, total)+"%");

var total = 1000,
subtract = 284;
var differencePercentage = ((total - subtract) / total) * 100; // 71.6

Simple math would be
var now = 284;
var total = 1000;
console.log( "percentage is " + (now* 100/total) );
console.log( "Negative percentage is " + (100-(now* 100/total)) );

(function(){
var now = 284;
var total = 1000;
var difference = ((total - now) / total) * 100;
alert(difference);
})()
