Array filtering faster than the native array.filter method
npm install fast-filterA replacement for the native [].filter method that performs 5-10 times faster in most environments.
``bash`
npm install fast-filter
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]
