lodash.intersection

What is lodash.intersection?

The lodash.intersection package is a utility library that provides a function to compute the intersection of multiple arrays. This means it returns an array of values that are present in all of the provided arrays.

What are lodash.intersection's main functionalities?

Array Intersection

This feature allows you to find the common elements in multiple arrays. In the provided code sample, the intersection of array1, array2, and array3 is computed, resulting in [3], which is the only element present in all three arrays.

const intersection = require('lodash.intersection');
const array1 = [1, 2, 3];
const array2 = [2, 3, 4];
const array3 = [3, 4, 5];
const result = intersection(array1, array2, array3);
console.log(result); // Output: [3]

Other packages similar to lodash.intersection

underscore

The underscore package is a JavaScript utility library that provides a wide range of functions for common programming tasks, including array manipulation. The _.intersection function in underscore works similarly to lodash.intersection, allowing you to find the common elements in multiple arrays.

ramda

Ramda is a functional programming library for JavaScript that provides a variety of utility functions. The R.intersection function in Ramda can be used to find the intersection of two arrays. Unlike lodash.intersection, which can handle multiple arrays, Ramda's R.intersection is designed to work with two arrays at a time.

array-intersection

The array-intersection package is a lightweight utility specifically designed to find the intersection of arrays. It provides a simple and focused solution for this specific task, similar to lodash.intersection, but without the additional utilities that lodash offers.
