pluralize

What is pluralize?

The pluralize npm package is a simple utility for converting words between their singular and plural forms. It can also handle irregular forms and uncountable nouns.

What are pluralize's main functionalities?

Pluralization

Converts a singular noun to its plural form, or vice versa, depending on the count provided. It also correctly handles uncountable nouns.

const pluralize = require('pluralize');
console.log(pluralize('fish')); // 'fish'
console.log(pluralize('fish', 5)); // 'fish'
console.log(pluralize('fish', 1)); // 'fish'

Singularization

Converts a plural noun to its singular form.

const pluralize = require('pluralize');
console.log(pluralize.singular('wolves')); // 'wolf'

Adding Irregular Rules

Allows the addition of custom irregular rules for nouns that do not follow the normal pluralization pattern.

const pluralize = require('pluralize');
pluralize.addIrregularRule('goose', 'geese');
console.log(pluralize('goose')); // 'geese'

Adding Uncountable Rules

Allows the addition of uncountable rules for nouns that should not be pluralized.

const pluralize = require('pluralize');
pluralize.addUncountableRule('equipment');
console.log(pluralize('equipment')); // 'equipment'
