ReactJS Moment is not formatting date correctly












2














I have a function for displaying the first date of the week and it's result are displayed as followed:



Mon Nov 12 2018 08:14:09 GMT-0600 (Central Standard Time)



...what am attempting to do is display the result with the month only:
2018-11-12



...here is the function for getting the first day of the week:



let sd = new Date();
const startOfWeek = (date) => {
let diff = date.getDate() - date.getDay() + (date.getDay() === 0 ? -6 : 1);
return new Date(date.setDate(diff));
}


...I call the function as followed:



const startDay = startOfWeek(sd).toString();


...Here is where I Use moment to apply the formatting:



moment(startDay).format('YYYY MMMM Do');


...but my date still displays the following:
Mon Nov 12 2018 08:14:09 GMT-0600 (Central Standard Time)



...could I get some help as to what am doing wrong?

    The .format() function returns the formatted string. It does not forever establish the formatting for the object.

    You might also want to look at Luxon, as it uses immutable objects, which might be a better fit for React.

  • Can you add more code where you use the line moment(startDay).format('YYYY MMMM Do'); please? It's not clear why you are getting the output "Mon Nov 12 2018 08:14:09 GMT-0600 (Central Standard Time)" having looked at your moment format string.

This should work, the format was incorrect though, it should be YYYY-MM-D



let sd = new Date();
const startOfWeek = (date) => {
let diff = date.getDate() - date.getDay() + (date.getDay() === 0 ? -6 : 1);
return new Date(date.setDate(diff));
}
const startDay = startOfWeek(sd)
console.log(moment(startDay).format('YYYY-MM-D'));

I think the moment js format you are looking for is:



moment(startDay).format('YYYY-MM-DD');



The format YYYY MMMM Do would return a string like: "2018 November 13th".

This should work, the format was incorrect though, it should be YYYY-MM-D



let sd = new Date();
const startOfWeek = (date) => {
let diff = date.getDate() - date.getDay() + (date.getDay() === 0 ? -6 : 1);
return new Date(date.setDate(diff));
}
const startDay = startOfWeek(sd)
console.log(moment(startDay).format('YYYY-MM-D'));

I think the moment js format you are looking for is:



moment(startDay).format('YYYY-MM-DD');



The format YYYY MMMM Do would return a string like: "2018 November 13th".
