array-sample
An array extension to sample random elements from an array. Ask for one, get a random element, ask for multiple elements and get an array. Since the samples are random, it's good to remember that they won't be in any meaningful order.
Install
npm install array-sample
Usage
Array.prototype.sample = require('array-sample');
[0,1,2].sample() // 1
[0,1,2].sample() // 0
[0,1,2].sample() // 1
[0,1,2].sample(1) // 2
[0,1,2].sample(5) // [1,2,0,0,2]
That's it
