See the Intl.DateTimeFormat() constructor for details on these parameters and how to use them. In implementations without Intl.DateTimeFormat support, this parameter is ignored. If weekday, year, month, and day are all undefined, then year, month, and day will be set to "numeric". The timeStyle option must be undefined, or a TypeError would be thrown. Corresponds to the options parameter of the Intl.DateTimeFormat() constructor. options OptionalĪn object adjusting the output format. In implementations without Intl.DateTimeFormat support, this parameter is ignored and the host's locale is usually used. ![]() Corresponds to the locales parameter of the Intl.DateTimeFormat() constructor. locales OptionalĪ string with a BCP 47 language tag, or an array of such strings. Implementations without Intl.DateTimeFormat support are asked to ignore both parameters, making the locale used and the form of the string returned entirely implementation-dependent. In implementations that support the Intl.DateTimeFormat API, these parameters correspond exactly to the Intl.DateTimeFormat() constructor's parameters. The locales and options arguments customize the behavior of the function and let applications specify the language whose formatting conventions should be used. Object.prototype._lookupGetter_() Deprecated.Object.prototype._defineSetter_() Deprecated.Object.prototype._defineGetter_() Deprecated.However, calling () on non- Date objects fails unless the object's number primitive representation is NaN, or the object also has a toISOString() method. Note that the method does not check whether the this value is a valid Date object. ![]() (This generally corresponds to an invalid date, whose valueOf() returns NaN.) Otherwise, if the converted primitive is not a number or is a finite number, the return value of this.toISOString() is returned. If the result is a non-finite number, null is returned. The method first attempts to convert its this value to a primitive by calling its (with "number" as hint), valueOf(), and toString() methods, in that order. This method is generally intended to, by default, usefully serialize Date objects during JSON serialization, which can then be deserialized using the Date() constructor as the reviver of JSON.parse(). The toJSON() method is automatically called by JSON.stringify() when a Date object is stringified.
