What is moment?

The moment npm package is a JavaScript library for parsing, validating, manipulating, and formatting dates. It is widely used for handling dates and times in Node.js and browser applications.

What are moment's main functionalities?

Parsing

Parse a date string into a moment object.

moment('2023-04-05')

Validation

Check if a date is valid.

moment('2023-04-05').isValid()

Manipulation

Manipulate dates by adding time to the current date.

moment().add(7, 'days')

Formatting

Format a moment date object into a string in a specified format.

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

Query

Query dates to compare them.

moment().isBefore('2023-12-25')
