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. * * @typeParam DateType - The `Date` type, the function operates on. Gets inferred from passed arguments. Allows to use extensions like [`UTCDate`](https://github.com/date-fns/utc). * * @param date - The date to be changed * @param values - The date values to be set * * @returns The new date with options set * * @example * // Transform 1 September 2014 into 20 October 2015 in a single line: * const 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: * const result = set(new Date(2014, 8, 1, 1, 23, 45), { hours: 12 }) * //=> Mon Sep 01 2014 12:23:45 */ export function set(date, values) { let _date = toDate(date); // Check if date is Invalid Date because Date.prototype.setFullYear ignores the value of Invalid Date if (isNaN(+_date)) { return constructFrom(date, NaN); } if (values.year != null) { _date.setFullYear(values.year); } if (values.month != null) { _date = setMonth(_date, values.month); } if (values.date != null) { _date.setDate(values.date); } if (values.hours != null) { _date.setHours(values.hours); } if (values.minutes != null) { _date.setMinutes(values.minutes); } if (values.seconds != null) { _date.setSeconds(values.seconds); } if (values.milliseconds != null) { _date.setMilliseconds(values.milliseconds); } return _date; } // Fallback for modularized imports: export default set;
