Example: ```js var uniqs = require('uniqs'); var foo = { foo: 23 }; var list = [3, 2, 2, 1, foo, foo]; uniqs(list); // => [3, 2, 1, { foo: 23 }] ``` You can pass multiple lists to create a union: ```js uniqs([2, 1, 1], [2, 3, 3, 4], [4, 3, 2]); // => [2, 1, 3, 4] ``` Passing individual items works too: ```js uniqs(3, 2, 2, [1, 1, 2]); // => [3, 2, 1] ``` ### Summary * Uniqueness is defined based on strict object equality. * The lists do not need to be sorted. * The resulting array contains the items in the order of their first appearance. ### About This package has been written to accompany utilities like [flatten](https://npmjs.org/package/flatten) as alternative to full-blown libraries like underscore or lodash. The implementation is optimized for simplicity rather than performance and looks like this: ```js module.exports = function uniqs() { var list = Array.prototype.concat.apply([], arguments); return list.filter(function(item, i) { return i == list.indexOf(item); }); }; ``` ### License MIT package/index.js000644 000765 000024 0000000264 12343302352012173 0ustar00000000 000000 module.exports = function uniqs() { var list = Array.prototype.concat.apply([], arguments); return list.filter(function(item, i) { return i == list.indexOf(item); }); }; package/test.js000644 000765 000024 0000001110 12343303234012032 0ustar00000000 000000 var uniqs = require('./'); var util = require('util'); var assert = require('assert'); var foo = { foo: 23 }; [ [ [[2, 1, 1], [2, 3, 3, 4], [4, 3, 2]], [2, 1, 3, 4] ], [ [3, 2, 2, [1, 1, 2]], [3, 2, 1] ], [ [[2, 2, 3, "a", 3, 1, foo, foo, "a" ]], [ 2, 3, "a", 1, foo ] ], [ [23], [23] ], [ [], [] ], [ [[]], [] ], [ [[null], null], [null] ] ] .forEach(function(t) { var args = t[0].map(JSON.stringify); assert.deepEqual(uniqs.apply(this, t[0]), t[1], util.format('✘ uniqs(%s) !== %j', args, t[1]) ); console.log('✔ uniqs(%s) == %j', args, t[1]); }); package/.travis.yml000644 000765 000024 0000000044 12342720623012637 0ustar00000000 000000 language: node_js node_js: - 0.10
