Power Set Generator

Javascript utility that creates generator which yields power set of provided values, from simplest to most complex combinations, in stable order.

For example, providing this list...

['a', 'b', 'c']

...will produce these combinations, in this order:

[ 'a' ]
[ 'b' ]
[ 'c' ]
[ 'a', 'b' ]
[ 'a', 'c' ]
[ 'b', 'c' ]
[ 'a', 'b', 'c' ]

How to use

Install from NPM:

npm install @fczbkk/power-set-generator

Then include it in your code:

import PowerSetGenerator from '@fczbkk/power-set-generator';

Then you can use it like any other generator.

In a loop:

const generator = PowerSetGenerator(['a', 'b', 'c'])
for (const result of generator) {
    console.log(result)
}

Via iteration protocol:

const generator = PowerSetGenerator(['a', 'b', 'c'])

let result = generator.next()
while (!result.done) {
  console.log(result.value)
  result = generator.next()
}

Or you can generate whole set at once:

const generator = PowerSetGenerator(['a', 'b', 'c'])
const result = [...generator]
