Move false to variable to improve performance and use false-value library

[tj-commits]

It would be better if performance was optimized by moving the true and arrow function to variables.

heres what the code should be

let False = require('false-value')
then
let f = () => False
and finally
module.exports = f

false-value is a library that will get the value of "false" for you, following the single responsibility principle.
