How to convert month year (YYYYmm) string to Datetime in Javascript?-CodePudding

I have a Year and Month string "202008" which I need to convert into DateTime like 2020-08-01 00:00:00. What would be the best way to do it using Javascript or Momentjs?

CodePudding user response：

You can specify the input format in moment by using the second argument. moment(input, format)

moment('082020', 'MY').format('YYYY-MM-DD HH:mm:ss');
// 2020-08-01 00:00:00

Using plain JS

function toDate(str) {
  const d = new Date(str.replace(/(\d\d)(\d{4})/, "$2-$1-01T00:00:00"));
  // en-ca because Canadians do dates like yyyy-mm-dd
  return new Intl.DateTimeFormat('en-CA', {
    dateStyle: "short",
    timeStyle: 'medium',
    hour12:false,
    hourCycle: 'h23',
  }).format(d).replace(',', '');
}
console.log(toDate("082020"));
