* @category Common Helpers
|
|
* @summary Format the date according to the ISO 3339 standard (https://tools.ietf.org/html/rfc3339#section-5.6).
|
|
*
|
|
* @description
|
|
* Return the formatted date string in ISO 3339 format. Options may be passed to control the parts and notations of the date.
|
|
*
|
|
* @param {Date|Number} date - the original date
|
|
* @param {Object} [options] - an object with options.
|
|
* @param {0|1|2|3} [options.fractionDigits=0] - number of digits after the decimal point after seconds
|
|
* @returns {String} the formatted date string
|
|
* @throws {TypeError} 1 argument required
|
|
* @throws {RangeError} `date` must not be Invalid Date
|
|
* @throws {RangeError} `options.fractionDigits` must be between 0 and 3
|
|
*
|
|
* @example
|
|
* // Represent 18 September 2019 in ISO 3339 format:
|
|
* const result = formatRFC3339(new Date(2019, 8, 18, 19, 0, 52))
|
|
* //=> '2019-09-18T19:00:52Z'
|
|
*
|
|
* @example
|
|
* // Represent 18 September 2019 in ISO 3339 format, 2 digits of second fraction:
|
|
* const result = formatRFC3339(new Date(2019, 8, 18, 19, 0, 52, 234), { fractionDigits: 2 })
|
|
* //=> '2019-09-18T19:00:52.23Z'
|

*
|
|
* @example
|
|
* // Represent 18 September 2019 in ISO 3339 format, 3 digits of second fraction
|
|
* const result = formatRFC3339(new Date(2019, 8, 18, 19, 0, 52, 234), { fractionDigits: 3 })
