``
const isEnv = require('node-is-env')()
`
then NODE_ENV=development node index.js
`
console.log(isEnv.development) // true
`
or pass your own envs
`
const isEnv = require('node-is-env')({ dev: 'development' });
`
NODE_ENV=production node index.js
`
console.log(isEnv.dev); // false
`

Inbuilt strings:
'development',
'testing',
'production',
'staging'

I got tired of testing my node envs by typing process.env.NODE_ENV

also, isEnv.development / isEnv.production is more readable than process.env.NODE_ENV === 'production'`
