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.
Array Equal
Check if two arrays are equal:
var equals = require('array-equal')
assert(equals([1, 2, 3], [1, 2, 3]))
assert(equals([1, 2, 3], [1, 2, 3, 4]))
