moment.normalizeUnits(String);
Many of Moment's functions allow the caller to pass in aliases for unit enums. For example, all of the get
s below are equivalent.
var m = moment();
m.get('y');
m.get('year');
m.get('years');
If you're extending the library, you may want access to Moment's facilities for that in order to better align your functionality with Moment's.
moment.normalizeUnits('y'); // 'year'
moment.normalizeUnits('Y'); // 'year'
moment.normalizeUnits('year'); // 'year'
moment.normalizeUnits('years'); // 'year'
moment.normalizeUnits('YeARS'); // 'year'
