格式已弃用警告-但我正在指定格式

Question

Using moment.js, I keep getting the format warning in the browser console:

Deprecation warning: value provided is not in a recognized RFC2822 or ISO format. moment construction falls back to js Date(), which is not reliable across all browsers and versions. Non RFC2822/ISO date formats are discouraged and will be removed in an upcoming major release. Please refer to http://momentjs.com/guides/#/warnings/js-date/ for more info. Arguments:

But as far as I can tell, I specified the format as per the docs:

const checkToday = (targetDate)=> {
  return chartData
    .filter(curve => moment(curve.date, "MM-DD-YYYY").isBefore(targetDate, 'day'));
};

if (chartData) {
  // addd # days to today
  const targetDate = moment().add(days, 'days').format('MM-DD-YYYY');
  return checkToday(targetDate);
}

Where is it complaining that I am not specifying the format?

Answer 1

The problem is in this line:

.filter(curve => moment(curve.date, "MM-DD-YYYY").isBefore(targetDate, 'day'));

You are passing a string to .isBefore that is created in this line:

const targetDate = moment().add(days, 'days').format('MM-DD-YYYY');

The format you are using for that string "MM-DD-YYYY" is what moment is complaining about. Acceptable formats are found here
