wrandom
Get a random element from a weighted array.
Installation
$ npm install wrandom
Usage
const wrandom = require('wrandom');
let arr = ['foo', 'bar', 'baz'];
// first argument is an array of values
// second argument is an array of relative weights
wrandom(arr, [4, 6, 10]); // same weights as [0.2, 0.3, 0.5]
Omitting the second argument returns a random element from the array, assuming an even weighting:
wrandom(arr); // same weights as [1, 1, 1]
