This is meant to be small and stupidly simple.
For the absolutely simplest alternative, see sorp.
For smarter/bigger options, you've got:
npm install --save plural-for
var pluralFor = require('plural-for')
var asWord = require('zero-to-nine').asWord
let nOcelots = 0
let nWolves = 2
console.log(`There will be ${asWord(nOcelots)} ${pluralFor(nOcelots, 'ocelot')} left after building the wall.`)
// output: "There will be zero ocelots left after building the wall."
console.log(`There will be only ${asWord(nWolves)} Mexican gray ${pluralFor(nWolves, 'wolf', 'wolves')} left, sadly.`)
// output: There will be only two Mexican gray wolves left, sadly.
