Package description
The array-union package is designed to create an array of unique values, in order, from all given arrays. It's particularly useful for combining arrays while removing duplicate entries, ensuring that the resulting array contains only unique items.
Creating a union of arrays
This feature allows you to combine multiple arrays into one array with unique values, effectively removing duplicates.
const arrayUnion = require('array-union');
const result = arrayUnion([1, 2], [2, 3], [3, 4]);
console.log(result); // Output: [1, 2, 3, 4]Lodash's union function offers similar functionality to array-union by creating an array of unique values, in order, from all given arrays. Lodash is a more comprehensive utility library, so using lodash.union might be preferable if you're already using Lodash in your project.
Underscore.js provides a union function that combines multiple arrays into one array of unique values, similar to array-union. Like Lodash, Underscore is a broader utility library, so it might be a better choice if you need other utility functions beyond array union.
