@arr/filter

@arr/filter

A tiny, faster alternative to native Array.prototype.filter

Unlike native, @arr/filter does not support the optional thisArg parameter!

If you are okay with mutating the original, check out @arr/filter.mutate for an extremely fast filter alternative!

Install

$ npm install --save @arr/filter

Usage

import filter from '@arr/filter';

const words = ['foo', 'bar', 'baz', 'foobar', 'hello', 'world'];

filter(words, str => str.length > 3);
//=> ['foobar', 'hello', 'world']

console.log(words);
//=> ['foo', 'bar', 'baz', 'foobar', 'hello', 'world']
