|
*
|
|
* @description
|
|
* Set date values to a given date.
|
|
*
|
|
* Sets time values to date from object `values`.
|
|
* A value is not set if it is undefined or null or doesn't exist in `values`.
|
|
*
|
|
* Note about bundle size: `set` does not internally use `setX` functions from date-fns but instead opts
|
|
* to use native `Date#setX` methods. If you use this function, you may not want to include the
|
|
* other `setX` functions that date-fns provides if you are concerned about the bundle size.
|
|
*
|
|
* @param {Date|Number} date - the date to be changed
|
|
* @param {Object} values - an object with options
|
|
* @param {Number} [values.year] - the number of years to be set
|
|
* @param {Number} [values.month] - the number of months to be set
|
|
* @param {Number} [values.date] - the number of days to be set
|
|
* @param {Number} [values.hours] - the number of hours to be set
|
|
* @param {Number} [values.minutes] - the number of minutes to be set
|
|
* @param {Number} [values.seconds] - the number of seconds to be set
|
|
* @param {Number} [values.milliseconds] - the number of milliseconds to be set
|
|
* @returns {Date} the new date with options set
|
|
* @throws {TypeError} 2 arguments required
|
|
* @throws {RangeError} `values` must be an object
|
|
*
|
|
* @example
|
|
* // Transform 1 September 2014 into 20 October 2015 in a single line:
|
|
* var result = set(new Date(2014, 8, 20), { year: 2015, month: 9, date: 20 })
|
|
* //=> Tue Oct 20 2015 00:00:00
|
|
*
|
|
* @example
|
|
* // Set 12 PM to 1 September 2014 01:23:45 to 1 September 2014 12:00:00:
|
|
* var result = set(new Date(2014, 8, 1, 1, 23, 45), { hours: 12 })
|
|
* //=> Mon Sep 01 2014 12:23:45
