When working with dates and times in JavaScript, the Moment.js library is a popular choice due to its flexibility and ease of use. One common requirement is to display only the date or time component of a Moment.js object.

Displaying Only the Date Component

To display only the date component of a Moment.js object, you can use the format() function along with the 'YYYY-MM-DD' format string. Here’s an example:

const moment = require('moment');

const dateTime = moment(); // Current date and time
const dateOnly = dateTime.format('YYYY-MM-DD');

console.log(dateOnly); // Output: 2022-07-20

In the example above, the format() function is called with the 'YYYY-MM-DD' format string, which specifies that only the year, month, and day components should be included in the output.

Displaying Only the Time Component

To display only the time component of a Moment.js object, you can use the format() function along with the 'HH:mm:ss' format string. Here’s an example:

const moment = require('moment');

const dateTime = moment(); // Current date and time
const timeOnly = dateTime.format('HH:mm:ss');

console.log(timeOnly); // Output: 23:45:30

In the example above, the format() function is called with the 'HH:mm:ss' format string, which specifies that only the hour, minute, and second components should be included in the output.

Conclusion

By utilizing the format() function with the appropriate format strings, you can easily control the precision of a Moment.js object and display only the date or time component as needed. This flexibility makes Moment.js a powerful tool for working with dates and times in JavaScript.
