Function: formatWeekNumber()
formatWeekNumber(
value,ctx):string
Defined in: time/format.ts:153
An ISO week label — W followed by the week number. The escape-hatch callback shipped as a
named value, because Intl has no week field. '' for a missing value.
Exported from api/ — unlike the individual preset constants — because a custom-
preset author cannot produce a week number any other way.
Parameters
value
unknown

Returns
string
