You Probably Don t Need Moment js Anymore Moment is great time manipulation library but it s considered as a legacy project  and the team is recommending to use other libraries  date-fns is one of the best lightweight libraries  it s modular  so you can pick the functions you need and reduce bundle size  issue  amp  statement    Another common argument against using Moment in modern applications is its size  Moment doesn t work well with modern  quot tree shaking quot  algorithms  so it tends to increase the size of web application bundles   import   format   from  date-fns     21K  gzipped  5 8K  import moment from  moment     292 3K  gzipped  71 6K   Format date with date-fns     moment js moment   format  MM DD YYYY         gt   quot 12 18 2020 quot      date-fns import   format   from  date-fns  format new Date     MM dd yyyy         gt   quot 12 18 2020 quot   More on cheat sheet with the list of functions which you can use to replace moment js  You-Dont-Need-Momentjs

For fromating output date use format  Second moment argument is for parsing - however if you omit it then you testDate will cause deprecation warning     Deprecation warning  value provided is not in a recognized RFC2822 or ISO format       x000D   x000D  var testDate   Fri Apr 12 2013 19 08 55 GMT-0500  CDT   x000D   x000D  let s  moment testDate  format  MM DD YYYY    x000D   x000D  msg innerText  s  x000D   lt script src  https   cdnjs cloudflare com ajax libs moment js 2 24 0 moment min js  gt  lt  script gt  x000D   x000D   lt div id  msg  gt  lt  div gt  x000D   x000D   x000D    to omit this warning you should provide parsing format   x000D   x000D  var testDate   Fri Apr 12 2013 19 08 55 GMT-0500  CDT   x000D   x000D  let s  moment testDate   ddd MMM D YYYY HH mm ss ZZ   format  MM DD YYYY    x000D   x000D  console log s   x000D   lt script src  https   cdnjs cloudflare com ajax libs moment js 2 24 0 moment min js  gt  lt  script gt  x000D   x000D   x000D

May be this helps some one who are looking for multiple date formats one after the other by willingly or unexpectedly  Please find the code  I am using moment js format function on a current date as  today is 29-06-2020  var startDate   moment new Date    format  MM DD YY    Result  06 28 20 what happening is it retains only the year part  20 as  quot 06 28 20 quot   after If I run the statement   new Date startDate  The result is  quot Mon Jun 28 1920 00 00 00 GMT 0530  India Standard Time  quot   Then  when I use another format on  quot 06 28 20 quot   startDate   moment startDate   format  MM-DD-YYYY    Result  06-28-1920  in google chrome and firefox browsers it gives correct date on second attempt as  06-28-2020  But in IE it is having issues  from this I understood we can apply one dateformat on the given date  If we want second date format  it should be apply on the fresh date not on the first date format result  And also observe that for first time applying  MM-DD-YYYY  and next  MM-DD-YY  is working in IE  For clear understanding please find my question in the link  Date went wrong when using Momentjs date format in IE 11

The 2nd argument to moment   is a parsing format rather than an display format   For that  you want the  format   method   moment testDate  format  MM DD YYYY      Also note that case does matter  For Month  Day of Month  and Year  the format should be uppercase
