A module that actually returns a real no-op function
npm install true-noop   
The only _true_ 'no operation' module out there.
Installation
``javascript`
npm install --save true-noop
Usage
`javascript
let noop = require('true-noop');
noop();
`

What makes this a _true_ 'no operation' function?
While other 'no-op' modules actually go ahead and create then return a new function, e.g.
module.exports = function() {}
module.exports = () => () => {};
true-noop exploits the fact that Function.prototype is in itself a function that does nothing and returns undefined.
module.exports = Function.prototype;`
