formatToPartsdate

formatToPartsdate is commonly understood as a misnomer for the Intl.DateTimeFormat.formatToParts method, a function in the ECMA-402 internationalization API. There is no standard API named formatToPartsdate; formatToParts is the correct method name. It formats a date according to a specified locale and options and returns the result as an array of parts rather than a single string.

The formatToParts method belongs to Intl.DateTimeFormat. Its usage involves creating a formatter with a locale and formatting options, then calling formatToParts with a Date object or a numeric timestamp. The returned value is an array where each element is an object with a type and a value. The type indicates the kind of date/time component (for example year, month, day, hour, minute, second, dayPeriod, weekday, era), or it can be a literal string that should appear as-is in the final result. The exact set of types depends on the locale and options chosen.

Common scenarios include extracting individual date parts for custom assembly, localization testing, or supplying parts to a rendering system that builds its own UI. Because formatToParts is locale-aware, the sequence and formatting of parts can vary between languages and scripts, unlike a fixed date string.

Example usage (conceptual): a formatter for en-US with numeric year, two-digit month, and two-digit day may produce parts like [{type:'month', value:'09'},{type:'literal', value:'/'},{type:'day', value:'08'},{type:'literal', value:'/'},{type:'year', value:'2024'}]. The exact output depends on locale and options.

FormatToParts is broadly supported in modern browsers and environments implementing the ECMA-402 API. For older runtimes, availability may vary.
