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.
