Day.js is a JavaScript library that lets us manipulate dates in our apps.
In this article, we’ll look at how to use Day.js to manipulate dates in our JavaScript apps.
Get Different Date Values
We can get different date values with the get method and the unit of the date part to get as the argument.
For instance, we write:
const dayjs = require("dayjs");
const result = [
dayjs().get("year"),
dayjs().get("month"),
dayjs().get("date"),
dayjs().get("hour"),
dayjs().get("minute"),
dayjs().get("second"),
dayjs().get("millisecond")
];
console.log(result);
to get the year, month, date of the month, hour, minute, second, and milliseconds of a date with the get method and the 'year' , 'month' , 'date' , 'hour' , 'minute' , 'second' , and 'millisecond' respectively.
The month starts with 0 for January just like JavaScript dates.
There’re also shorthands for each argument string.
'y' is shorthand for 'year' .
'M' is shorthand for 'month' .
'D' is shorthand for 'date' .
'd' is shorthand for 'day' , which is the day of the week. It starts at 0 for Sunday, and 6 is Saturday.
'h' is shorthand for 'hour' .
'm' is shorthand for 'minute' .
's' is shorthand for 'second' .
And 'ms' is shorthand for 'millisecond' .
Conclusion
Day.js is a JavaScript library that lets us manipulate dates in our apps.
