reduce-flatten

DEPRECATED: Please use the Array.prototype.flat() method built into ES2019 and above.

Isomorphic map-reduce function to flatten an array into the supplied array.

Example

const flatten = require('reduce-flatten')

Kind: Exported function
Example

> numbers = [ 1, 2, [ 3, 4 ], 5 ]
> numbers.reduce(flatten, [])
[ 1, 2, 3, 4, 5 ]

This library is compatible with Node.js, the Web and any style of module loader. It can be loaded anywhere, natively without transpilation.

Node.js:

const arrayify = require('reduce-flatten')

Within Node.js with ECMAScript Module support enabled:

import arrayify from 'reduce-flatten'

Within an modern browser ECMAScript Module:

import arrayify from './node_modules/reduce-flatten/index.mjs'

Old browser (adds window.flatten):

<script nomodule src="./node_modules/reduce-flatten/dist/index.js"></script>
