array-equal

What is array-equal?

The array-equal npm package is a simple utility for checking if two arrays are equal. It performs a deep comparison to determine if the arrays contain the same elements in the same order.

What are array-equal's main functionalities?

Basic Array Equality Check

This feature allows you to check if two arrays are equal by comparing their elements in order. If all elements match, it returns true; otherwise, it returns false.

const arrayEqual = require('array-equal');
const arr1 = [1, 2, 3];
const arr2 = [1, 2, 3];
console.log(arrayEqual(arr1, arr2)); // true

Nested Array Equality Check

This feature allows you to check if two nested arrays are equal. It performs a deep comparison to ensure that all nested elements match.

const arrayEqual = require('array-equal');
const arr1 = [1, [2, 3], 4];
const arr2 = [1, [2, 3], 4];
console.log(arrayEqual(arr1, arr2)); // true

Other packages similar to array-equal

deep-equal

The deep-equal package provides a more comprehensive deep comparison between two values, including arrays, objects, and other data types. It is more versatile than array-equal as it can handle a wider range of comparisons.

fast-deep-equal

The fast-deep-equal package is optimized for performance and provides a fast way to perform deep equality checks. It is similar to array-equal but is designed to be faster and more efficient.

lodash.isequal

The lodash.isequal function from the Lodash library provides a deep comparison between two values to determine if they are equivalent. It is part of the larger Lodash utility library, which offers a wide range of utility functions beyond equality checks.
