            Sorting and ordering an array with different criteria
            Asked 2022-Apr-08 at 12:05

            I am trying to implement sorting and order to an array.

            The challenge which I am facing is that I have 5 criteria on which to base my sorting, which are:

            1. due_date === 1000
            2. status && is_approved(boolean)
            3. is_overdue(boolean checking with date-fns using the due_date)
            4. due_date (either null, or number)
            5. is_approved

            What I would like to achieve is to create a sorting function which orders the above criteria as the following (from highest to lowest):

            1. due_date === 1000

            2. is_overdue (I am using isAfter of the date-fns which returns a boolean)

            3. status === 'DONE' && !is_approved

            4. due_date starting from lowest to highest (ignore the null values)

            5. is_approved === true

            6. any other remaining object

            I was thinking of perhaps running .map method, and appending a ranking value for each of the object by checking the criteria, but there must be a way of doing this in single iteration with .sort method. I already checked other StackOverflow threads, but most of their data is relatively simple such as age, name etc.



            Answered 2022-Apr-08 at 11:32

            You just need to define a sorting function

            I've implemented the first two requirements I leave the rest to you

            Probably it needs a bit of refactoring but you get the idea



            IF/ELSE condition not working properly and Rerendring duplicates React
            Asked 2022-Mar-26 at 20:01

            My goal here is to check a checkin and checkout date and see if a room is available or not

            if availdata[p.roomId][date].i==0 then the room at that range of dates is not available so it will be displayed as not available

            if not it will check its price with availdata[p.roomId][date].p1 and display it with a price instead

            Material UI (dateTime picker) : Invalid Date Format message after submission
            Asked 2022-Mar-16 at 07:51

            I am using Material Ui DateTime picker in a form. After submitting the form, I get the following error:

            Invalid Date Format


            I am using JSON Server in my react app for saving data.

            This is the output Element for the DateTime picker on DOM.



            Answered 2022-Mar-16 at 06:52

            It will probably not break if you remove the setDay(""); line from onSubmit. Why do you need it after all?



            addMonths fns is not returning correct UTC time
            Asked 2022-Mar-05 at 14:02

            I'm currently based in Central European Standard Time and I'm expecting to send all dates to the server converted back to UTC.

            I have tried simply using addMonths from date-fns library:



            Answered 2022-Mar-05 at 14:02

            The difference between CEST and UTC is simply one hour.

            The difference is two hours: Central European Summer Time (CEST, UTC+02:00).

            You went from CET time (one hour ahead) on Mar 05 2022 to CEST summer time (two hours ahead) on 2022-04-05.

            Central European Time (CET) is a standard time which is 1 hour ahead of Coordinated Universal Time (UTC).

            As of 2011, all member states of the European Union observe summer time (daylight saving time), from the last Sunday in March to the last Sunday in October. States within the CET area switch to Central European Summer Time (CEST, UTC+02:00) for the summer.

            Difference between date-fns' isValid and luxon's isValid
            Asked 2022-Feb-11 at 11:34

            As mentioned in my question. I really don't understand difference between date-fns' isValid and luxon's isValid. I have one date string variable and one variable which I invoke the date string with new Date().

            My date string is like this: Fri Feb 11 2022 02:00:00 GMT+0200 (Eastern European Standard Time)

            I have few questions:

            1. Why the date string is not valid both date-fns and luxon?

            2. The invoked date string variable with new Date() in date-fns it returns false but in luxon it return true

            I shared my code in codesand-box

            This is my all code

            Why is Ant Design throwing a Server Error when trying to use date-fns?
            Asked 2022-Feb-08 at 23:17

            After replacing Moment.js with date-fns using this guide from the antd documentation I get the next server error:

            Screenshot of error.

            SyntaxError: Cannot use import statement outside a module

            I've tried things like adding 'type': 'module' to the package.json and putting 'module': 'commonjs' in tsconfig.json and many other things but none seem to work.



            Answered 2022-Feb-08 at 23:17

            Got it. The solution was to replace 'antd/es/...' with 'antd/lib/...' in the imports provided in the documentation and the error was gone.

            Your DatePicker.tsx should look like this

            Get weekday list between two dates? JavaScript
            Asked 2022-Jan-20 at 03:53

            How to get weekday list between two dates? I need javaScript function for that. (date-fns library function also is Ok) as e example



            Answered 2022-Jan-20 at 03:53

            You can use a for loop to loop through each date between the start and end date, then use Date.getDay to get the day of the week and ignore the dates that are not a weekday.



            Getting error of "RangeError: Invalid time value" when inputing variable within new Date()

              const formattedEndDate = format(new Date(endDate), "dd, MMMM yyyy");
              const range = `${formattedStartDate} - ${formattedEndDate}`;
            export default search;


            Answered 2022-Jan-19 at 20:54

            I figured out my problem. Everything works fine and the code should have worked as intended. The problem was coming from using nextJs, useRouter(). To access the router I needed to use useRouter(), example: const router = useRouter();. Then to access the query data i've set up within the router would be such as: const { location, startDate, endDate, numOfGuests } = router.query;.

            To use useRouter it needs to be in a proper component function starting with a capitalized name. My problem was it was lowercased. Example ; function search() {...} instead of, function Search() {...}. From here i will keep the file name of search.js lowercased for address bar router query purposes.



            date-fns "RangeError: Invalid time value"
            Asked 2022-Jan-16 at 04:00

            I am trying to convert 18:00:00.000 to 24H (18:00) and 12H (6PM) formats using date-fns. However, the input value of 18:00:00.000 gives a "RangeError: invalid time value".

            My code



            Answered 2022-Jan-16 at 04:00

            Your code is failing because new Date() requires a valid date time string to create a new date object. To fix this, simply formulate a current date string and attach the timestamp you require and pass it to the new Date() method. Then you can pass the date object to the format method to get the desired output.

            Refer to this chart to format your dates as per your requirement.
