is-fn
Check if a value is a function
In Node.js, just use typeof fn
which works exactly the same. This module can be useful in the browser where typeof fn
has a myriad of bugs.
Install
$ npm install is-fn
Usage
import isFunction from 'is-fn';
isFunction(() => {});
//=> true
isFunction('unicorn');
//=> false
