fast-filter

A replacement for the native [].filter method that performs 5-10 times faster in most environments.

Install

``bash
npm install fast-filter
`

Basic usage


`js
var fastFilter = require('fast-filter');

fastFilter([1,2,3,4,5,6], function(val) { return val % 2; }); // [1,3,5]
`

"Installing" on the Array.prototype


You can add fastFilter to the native Array.prototype for convienience.
`js
require('fast-filter').install();

[1,2,3,4,5,6].fastFilter(function(val) { return val % 2; }); // [1,3,5]
`

Or provide an alias:
`js
require('fast-filter').install('select');

[1,2,3,4,5,6].select(function(val) { return val % 2; }); // [1,3,5]
`

Replacing the native filter method


You can replace the native Array.prototype.filter method, but keep in mind that this will modify the filter method for all code in this instance including any required modules and may result in unexpected behavior.
`js
require('fast-filter').install('filter');

[1,2,3,4,5,6].filter(function(val) { return val % 2; }); // [1,3,5]
