Moment .isAfter not returning correctly while comparing two dates

Question

I've got a problem with fucntion .isAfter(), when it comes to compare "05/04/2022" with "03/05/2022" it tells me that 05/04/2022>03/05/2022 I specified that I want to compare the whole date by adding 'day' in argument but nothing changes.. Can someone help me please ? Here is my code :

let date1 = moment("03-05-2022", "DD-MM-YYYY").format("DD-MM-YYYY");
data.forEach(d => {
  let test = date1;
  let date = moment(d.received_on).format("DD-MM-YYYY");
  const {
    adc_v,
  } = d;

  let dateIsAfter = moment(date).isAfter(moment(date1), 'day');
  let dateIsSame = moment(date).isSame(moment(date1), 'day');


  // const dateIsAfter = moment(date) > moment(date1);
  // const dateIsSame = moment(date) == moment(date1);


  if (dateIsSame === true) {
    this.arrTension.push({
      date,
      value: adc_v,
    });
    console.log(date + '  : ' + adc_v);
    date1 = moment(date1, "DD-MM-YYYY").add(1, 'days').format('DD-MM-YYYY');
  }
  if (dateIsAfter === true) {
    console.log('date = ' + date);
    console.log('date1 = ' + date1);
    date1 = moment(date1, "DD-MM-YYYY").add(1, 'days').format('DD-MM-YYYY');
  }
});

This is happening because you have not specified your locale.

When it compares 05/04/2022>03/05/2022, it is essentially checking 4th May 2022 is greater that 5th March 2022.

Specify the global locale as follows:

moment.locale('fr')

Then compare the dates as you were before:

moment(date).isAfter(moment(date1), 'day');
