uncertain

Flow control for indeterminate booleans as plain JS objects

Your API returns booleans, but sometimes a value is unknown. You want to have uncertain or null or true, but as plain javascript.

Install

$ npm install --save uncertain

var Uncertain = require('uncertain')

var value = Uncertain() // => 'uncertain'
Uncertain.is(value) // => true
