js-inflector

Word magic.

var inflector = require('js-inflector');

var inflect = inflector.start();

var someValue = 'tree';

Modify word state:

var plural = inflect(someValue, 'plural');  
//--> trees

var capital = inflect(someValue, 'capital');  
//--> Tree

Modify multiple word states at once:

var pluralAndCapital = inflect(someValue, ['capital', 'plural']);  
//--> Trees

Set a group state:

inflector.group({
  'properPlural': ['capital', 'plural']
});

With a group state:

var pluralAndCapital = inflect(someValue, 'properPlural');  
//--> Trees
