methods

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.
