array-uniq

What is array-uniq?

The array-uniq npm package is a simple and efficient utility for removing duplicate values from an array. It is designed to work with arrays containing primitive values such as strings, numbers, and booleans.

What are array-uniq's main functionalities?

Removing duplicates from an array

This feature allows you to pass an array to the array-uniq function, which then returns a new array with all duplicate values removed. It works with numbers, strings, and booleans.

const arrayUniq = require('array-uniq');
const uniqueArray = arrayUniq([1, 1, 2, 3, 3]);
console.log(uniqueArray); // Output: [1, 2, 3]

Other packages similar to array-uniq

lodash.uniq

lodash.uniq is part of the Lodash library, which provides a more comprehensive set of tools for working with arrays and objects. Unlike array-uniq, lodash.uniq supports arrays of objects and uses a custom comparator for uniqueness, which makes it more flexible but slightly slower for simple cases.

uniq

The uniq package offers similar functionality to array-uniq but includes additional features such as the ability to specify a custom iterator function to determine uniqueness. This can be useful for more complex comparison logic but adds overhead for simple use cases.

Create an array without duplicates

It's already pretty fast, but will be much faster when Set becomes available in V8 (especially with large arrays).

Install

$ npm install --save array-uniq

const arrayUniq = require('array-uniq');

arrayUniq([1, 1, 2, 3, 3]);
//=> [1, 2, 3]
