Cartesian product for big inputs.
Retrieves every possible combination between several arrays (cartesian product):
This module is perfect when you combine hundreds of arrays or when those arrays
produce millions of combinations. Otherwise you should use
fast-cartesian
instead as it is
much faster.
Please reach out if you're looking for a Node.js API or CLI engineer (11 years of experience). Most recently I have been Netlify Build's and Netlify Plugins' technical lead for 2.5 years. I am available for full-time remote positions.
import bigCartesian from 'big-cartesian'
for (const values of bigCartesian([
['red', 'blue'],
['circle', 'square'],
])) {
console.log(values)
}
// [ 'red', 'circle' ]
// [ 'red', 'square' ]
// [ 'blue', 'circle' ]
// [ 'blue', 'square' ]
You can try this library:
examples
files in a terminal.npm install big-cartesian
This package works in both Node.js >=18.18.0 and browsers.
This is an ES module. It must be loaded using
an import
or import()
statement,
not require()
. If TypeScript is used, it must be configured to
output ES modules,
not CommonJS.
inputs
: Array<Array | Iterable | GeneratorFunction>
Return value: Iterable<Array>
Iterates over each combination of inputs
.
This works with an infinite number of combinations.
Arrays in JavaScript have a size limit of 4 trillions of elements. You can bypass this limit by using iterables or generator functions instead.
import bigCartesian from 'big-cartesian'
const generator = function* () {
// This generator can generate an infinite number of elements
}
// Notice we pass the function itself: `generator` not `generator()`
for (const values of bigCartesian([['red', 'blue'], generator])) {
console.log(values)
}
