ES Module friendly fork of the definitive [JavaScript type testing library][is].

To be or not to be? This is the library!

Installation

As a node.js module

``shell
$ npm install es-is --save
`

Importing and usage with bundlers


Due to limitations with bundlers, rather than import {isFunction} from 'es-is'
it's recommended that you import from module directly: import isFunction from
'es-is/function. Hopefully as tree-shaking becomes more sophisticated, this
will become unnecessary.
