# example

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

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.
