[![browser support](http://ci.testling.com/substack/node-concat-map.png)](http://ci.testling.com/substack/node-concat-map) [![build status](https://secure.travis-ci.org/substack/node-concat-map.png)](http://travis-ci.org/substack/node-concat-map) example ======= ``` js var concatMap = require('concat-map'); var xs = [ 1, 2, 3, 4, 5, 6 ]; var ys = concatMap(xs, function (x) { return x % 2 ? [ x - 0.1, x, x + 0.1 ] : []; }); console.dir(ys); ``` *** ``` [ 0.9, 1, 1.1, 2.9, 3, 3.1, 4.9, 5, 5.1 ] ``` methods ======= ``` js var concatMap = require('concat-map') ``` concatMap(xs, fn) ----------------- Return an array of concatenated elements by calling `fn(x, i)` for each element `x` and each index `i` in the array `xs`. When `fn(x, i)` returns an array, its result will be concatenated with the result array. If `fn(x, i)` returns anything else, that value will be pushed onto the end of the result array. install ======= With [npm](http://npmjs.org) do: ``` npm install concat-map ``` license ======= MIT notes ===== This module was written while sitting high above the ground in a tree. node-concat-map-0.0.1/example/000077500000000000000000000000001227234037500161155ustar00rootroot00000000000000node-concat-map-0.0.1/example/map.js000066400000000000000000000002531227234037500172300ustar00rootroot00000000000000var concatMap = require('../'); var xs = [ 1, 2, 3, 4, 5, 6 ]; var ys = concatMap(xs, function (x) { return x % 2 ?
