I have a function that export excel so it works ver well what i am trying to do is
to have a header in the top excel file and it shows the date of export and under all data

what i tried this :

function RusaltsToCsv(results) {
let header = 'date'
let cols = [
'Name',
'Age'
]
let test = header;
header += new Date().toLocaleDateString()

let res = cols;
res += results.map(r => 
r.name +
r.age
)
return test + res
}

how it is possible to have header at top like this

    02.02.2022
name | Age
test | 20

I’m trying to make a task-scheduler that can read an a Google Sheet full of tasks (task name, start time, end time, person-assigned-to) and automatically create a calendar event on the specified person’s calendar.

This tutorial:https://cloud.google.com/blog/products/g-suite/g-suite-pro-tip-how-to-automatically-add-a-schedule-from-google-sheets-into-calendar

…has basically all I need, except that it only takes a single CalendarID, whereas I think I need the CalendarID to be part of the loop.

The CalendarID’s in this case are all email addresses.

Here’s what I tried:

function scheduleTasks() {
var spreadsheet = SpreadsheetApp.getActiveSheet();
var signups = spreadsheet.getRange("E9:H13").getValues();
for (x=0; x<signups.length;x++)
{
    var shift = signups[x];
    var calendarID = shift[3];
    var eventCal = CalendarApp.getCalendarById(calendarId);
    var task= shift[0];
    var startTime = shift[1];
    var endTime = shift[2];
    eventCal.createEvent(volunteer, startTime, endTime);
}
}

function onOpen() {
  var ui = SpreadsheetApp.getUi();
  ui.createMenu('Sync to Calendar')
  .addItem('Schedule tasks now', 'scheduleTasks')
  .addToUi();
}

And this is the error I’m getting:

8:38:40 AM Error TypeError: Cannot read property ‘createEvent’ of
null scheduleTasks @ Code.gs:12

Never used JS/Google Apps Script before now so any advice is appreciated,
Thanks

my input data

I am trying to create an extension to record screen. In manifest version 2 I was using a persistent background script and calling the start function with chrome.extension.getBackgroundPage() and everything was working perfectly. Now I am trying to migrate to v3 and having problems. Basically what I want to do is start screen record with chrome.desktopCapture in my background script for the active tab.

When I try to run chrome.desktopCapture in background.js chrome shut itself immediately. Since I cannot use getBackgroundPage anymore, I am passing message between the popup and background.

The Code:

// popup.html
chrome.runtime.sendMessage({
    message: "start", 
    tabId: <active-tab-id-here>
    }, (response) => {
           console.log(response.answer);
});

// background.js

chrome.runtime.onMessage.addListener( (request, _, sendResponse) => {
    switch(request.message) {
        case 'start':
               chrome.desktopCapture.chooseDesktopMedia(['tab', 'screen'], onAccessApproved);
    }
    
    sendResponse({answer: "Message Received Successfully!"});
}
);

i have this type of object of array

const obj =[{
        "id": 1,
        "language": "English",
        "language": "hindi",
        "language": "gujrati"
    }]

and i need to convert this object into this ,
all languages into array,

i want this output(javascript)

const obj =[{
        "id": 1,
        "language": ["English","hindi","gujrati"]
    }]

I have a json file with the following data which I would like to group by Year , Theme and then average values on each theme. Can someone help me with this? I have grouped by date and then theme but struggling after that.

[
{“Bid”:”BidTest1″,”QNo”:”1″,”Score”:”0.7″,”Theme”:”Social Value”,”QDate”:”01/01/2021″},
{“Bid”:”BidTest1″,”QNo”:”2″,”Score”:”0.5″,”Theme”:”Tech Mgt”,”QDate”:”01/01/2021″},
{“Bid”:”BidTest1″,”QNo”:”3″,”Score”:”0.8″,”Theme”:”Agile”,”QDate”:”01/01/2021″},
{“Bid”:”BidTest1″,”QNo”:”4″,”Score”:”0.7″,”Theme”:”Social Value”,”QDate”:”01/01/2021″},
{“Bid”:”BidTest456″,”QNo”:”1″,”Score”:”0.5″,”Theme”:”Tech Mgt”,”QDate”:”03/04/2021″},
{“Bid”:”BidTest456″,”QNo”:”2″,”Score”:”0.7″,”Theme”:”Social Value”,”QDate”:”03/04/2021″},
{“Bid”:”BidTest456″,”QNo”:”3″,”Score”:”0.5″,”Theme”:”Agile”,”QDate”:”03/04/2021″},
{“Bid”:”BidHO”,”QNo”:”1″,”Score”:”0.8″,”Theme”:”Agile”,”QDate”:”06/10/2021″},
{“Bid”:”BidHO”,”QNo”:”2″,”Score”:”0.7″,”Theme”:”Social Value”,”QDate”:”06/10/2021″},
]

The code I have used for grouping it is

        let result1 = dataQ1.reduce((state1, current1 ) => {
        let {QDate, Theme} = current1;
        
        let date = state1[QDate] || (state1[QDate] = {});
        let themeArr = date[Theme] || (date[Theme] = []);
       // let monthArr = yearObj[month] || (yearObj[month] = []);
        
        themeArr.push(current1);
        return state1;
     }, {});

This gives me an object with objects containing arrays for each Theme. I need to create a chart grouped by Month, Theme and mark the respective average values per theme.Final Data Sample.

Could someone please guide me on how to go about this ? Thanks

I am having array of objects where i want to reduce the array and get the count of two properties. When my array length is more than one it works but when its one or less it doesn’t

const data = [{id: 1, count:3 , alt_count: 2}, {id: 2, count:4 , alt_count: 5}];
const countObj = data.reduce((acc, curr) => {
      return {
        count_total: acc.count + curr.count,
        alt_count_total: acc.alt_count + curr.alt_count,
      };
    });
 console.log(countObj) // giving me both count_total and alt_count_total

But here its not giving me, instead it gives me the same object

const data = [{id: 1, count:3 , alt_count: 2}];
const countObj = data.reduce((acc, curr) => {
          return {
            count_total: acc.count + curr.count,
            alt_count_total: acc.alt_count + curr.alt_count,
          };
        });
console.log(countObj) // giving me entire first object

Any help is appreciated

My axios request

function fetchUsersFromLondon() {
  return axios
    .get("https://bpdts-test-app.herokuapp.com/city/London/users")
    .then((response) => {
      return response;
    })

}

module.exports = { fetchUsersFromLondon };

My Jest testing suite

const {fetchUsersFromLondon} = require(".././Models/fetchUsersFromLondon");

describe("Should return an array of objects of people from london", () => {
  test("should ", () => {
    expect(fetchUsersFromLondon()).toEqual([2]);
  });
});

My fetchUsersFromLondon function returns an empty object instead of the data from response. This error is not to do with incorrectly using axios or jest. I have narrowed it down to not returning out of the callback correctly. Any help is appreciated.

I have this function that checks whether something inside a certain div is clicked. A part of the function checks if the targeted button has a certain class. This works perfectly, but when I go to mobile it doesn’t work like I want it to.

btn.addEventListener("click", function (event) {
        if (!tgt.className.indexOf('nextbtn')) {
            navi.NextBtn();
            let dots = document.getElementsByClassName('owl-dots')[0];
            dots.style.display = 'block';
        }
})

I did a ! in the if statement because somehow it is reversed (I don’t know why). If I remove it it won’t do anything. On my computer it works perfectly, but when I go to mobile it doesn’t change the style to block, but it does run the NextBtn function. Does anybody know how to fix it?

I have a problem with my visual studio code, I cannoct use automatic switching programing language, for example I programing In php and can not writting HTML code without switch language to HTML by my hands(it doesnt work automaticaly). In status bar. I try uninstall and instal another version, but still doesnt working. Thanks for your time.enter image description here

I’m trying to implement a search of an object with multiple key/value pairs that can be either string or number.

This is what I’m currently using (simplified, of course):

const input = 'Hello WORld 21';   // this could also be a number
const search = 'RL';   // this could also be a number
let parsedInput = JSON.stringify(input).toLowerCase().replace(/(^"|"$)/g, '');
let parsedSearch = JSON.stringify(search).toLowerCase().replace(/(^"|"$)/g, '');

if(parsedInput.includes(parsedSearch)) {
  // do stuff
}

So this works, but seems to be expensive, especially when I go through tens of thousands of objects (or even more). So I wonder if there is a more elegant way to implement a search like this.

Thank you in advance!

I’m making a text adventure game that delves into certain rooms on a map. I want, upon entering a certain room, for the corresponding button entering that room to disappear, however, it does not seem to work.

Here is my Code:

                       room.innerHTML = "<h2>The Storage Room</h2>";
                       nar.innerHTML = "You enter the Storage Room. You're shocked to discover what's in there...Cages upon cages, stacked to the roof."
                       nar.innerHTML += "And the cages contain...fresh corpses. The smell violates your senses and you feel extremely nauseous."
                       nar.innerHTML += "<span style = 'color:red'>But there is a safe nearby...You could attempt to open it.</span>"
                       document.getElementById('melt_ice').removeAttribute('hidden');
                       document.getElementById('opening_safe').removeAttribute('hidden')

                       document.getElementById('open_safe').removeAttribute('hidden');
                       document.getElementById('storage_room').setAttribute('hidden','hidden');
                       document.getElementById('read_plaque').setAttribute('hidden','hidden')
break;

Can you help me identify where’s the problem with this code? I’m a beginner at coding and very likely I’m missing something obvious, but here’s my problem.

When clicking on numbers it seems to work fine, also adding gets to clear the display and (I think) it stores the value in its variable (operandA) but not getting the rest to work, nor the rest of the operands nor the “equals” button.

    </tr>
    </table>
<script type="text/javascript" src="function.js"></script>
</body>
</html>

Of course, it’s not finished. My aim is to keep on adding features to it, so as to learn while tweaking it.

Thanks in advance!

PS: Yes, there is a raw style sheet in CSS:

.calculator{
    display: block;
    margin: 0 auto;
    padding: 20px;
    background-color: rgb(207, 207, 207); 
    width: 340px;
    height: 580px;
    border-radius: 20px;
    box-shadow: 5px 5px 5px rgb(0, 0, 0);      
}

.calculator td button{
    display: block;
    background-color: rgb(161, 161, 161);
    text-align: center;
    width: 70px;
    height: 70px;
    font-size: 25px;
    border-radius: 100%;
    box-shadow: 2px 2px 2px rgb(0, 0, 0);
}
#equals{
    background-color: rgb(226, 189, 109);
}
#result{
    display: block;
    text-align: center;
    font-size: 40px;
    margin-bottom: 40px;
    width: 300px;
    height: 100px;
    line-height: 100px;
    background-color: aliceblue;
    border-radius: 15px;
    overflow-y:auto;
}

So i have this animation where there is this a h1 and when i scroll down the image zoom out and the h1 follow the image animation, my problem is that when im on mobile or i resize the screen to tablet or mobile i want the animation on scroll to not activate.
i already tried to use the resize function or if screen is > than but it doesn’t work i’m using scrollMagic cdn.

animation

JAVASCRIPT

/*==================== zoom out image ====================*/


let controller = new ScrollMagic.Controller();
let zoomHeader = TweenMax.to("#header", 0.9, { opacity: 1, scale: 0.35, ease: Circ.EaseIn });
let headerZoom = new ScrollMagic.Scene({
        triggerElement: "#header",
        triggerHook: 0,
        duration: "3000ms"
    })
    .setPin('#header')
    .setClassToggle('#header')
    .setTween(zoomHeader)

.addTo(controller);

/*==================== smooth link scrooling====================*/
let $root = $('html, body');

$('a[href^="#"]').click(function() {
    $root.animate({
        scrollTop: $($.attr(this, 'href')).offset().top
    }, 500);

    return false;
});


/*==================== Change opacity image ====================*/
$(window).scroll(function() {
    let scrollTop = $(this).scrollTop();

    $('#hero-ui').css({
        opacity: function() {
            let elementHeight = $(this).height();
            return 1 - (elementHeight - scrollTop) / elementHeight;
        }
    });
});

Imagine situation:

const [value, setValue] = useState(false);

const setSomething = (val) => {
  setValue((prev) => {
    fn(); dispatch(action); // or any other side effect
    
    return prev + val;
  });
};

Is it programmatically okey and fine with react principles to call side effects inside useState callback? May it affect the render process somehow?
