✖️ @set-theory/cartesian-product

Cartesian product for JavaScript. See docs.

⚠️ Depending on your environment, the code may require regeneratorRuntime to be defined, for instance by importing regenerator-runtime/runtime.

import { product } from '@set-theory/cartesian-product' ;
product( [ "ABCD" , "xy" ] , 1 ) ; // Ax Ay Bx By Cx Cy Dx Dy

import { range } from '@iterable-iterator/range' ;
product( [ range( 2 ) ] , 3 ) ; // 000 001 010 011 100 101 110 111

product( [ range( 4 ) , range( 4 ) ] ) ; // 00 01 02 03 10 11 12 13 20 21 ...

import { diagonal } from '@set-theory/cartesian-product' ;
diagonal( range( 4 ) , range( 4 ) ) ; // 00 01 10 02 11 20 03 12 21 30 ...

import { count } from '@iterable-iterator/count' ;
product( [count( ), count( )] ) ; // Loops forever without yielding. DO NOT DO THIS
diagonal( count( ), count( ) ) ; // 00 01 10 02 11 20 03 12 21 30 ...
import { _product } from '@set-theory/cartesian-product' ;
_product( [count( ), count( )], 0, 2 ) ; // 00 01 02 03 04 05 06 07 08 09 ...
