Advanced tools
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.
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
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.
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.
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.
Check if two arrays are equal
It checks that the elements and order are the same.
npm install array-equal
import arrayEqual from 'array-equal';
arrayEqual([1, 2, 3], [1, 2, 3]);
//=> true
arrayEqual([1, 2, 3], [1, 2, 3, 4]);
//=> false
