Generate array indices with round-robin distribution, weighted by given scores.
The package exposes a factory function which takes an array of weight scores and returns the arbiter function.
const wror = require('./'),
next = wror([ 2, 5, 3 ]),
counts = [ 0, 0, 0 ],
order = []
for (let i = 0; i < 10; i++) {
let n = next()
counts[ n ]++
order.push(n)
}
console.log(counts)
console.log(order.join(''))The result will be the following:
[ 2, 5, 3 ]
