check if 2 arrays are equal javascript

const a = [1, 2, 3];
const b = [4, 5, 6];
const c = [1, 2, 3];

function arrayEquals(a, b) {
  return Array.isArray(a) &&
    Array.isArray(b) &&
    a.length === b.length &&
    a.every((val, index) => val === b[index]);
}

arrayEquals(a, b); // false
arrayEquals(a, c); // true

Easy Way to Check if 2 Arrays are Equal in JavaScript

const d = [1,2,4,5,6];
const c = [1,2,4,5,6];

if (JSON.stringify(d) === JSON.stringify(c)) console.log('Equal!');

javascript check if two arrays contain same values

const a = ['Left', 'Right'];
const b = ['Right', 'Left'];

//	true if a and b contain the same values
//	false otherwise
const c = a.sort().join(',') === b.sort().join(',');

check if two array contains the same values js, array

const areEqual = (arr1, arr2) =>
  arr1.sort().join(',') === arr2.sort().join(',');
const arr1 = [1, 2, 3, 4];
const arr2 = [3, 4, 1, 2];
const arr3 = [1, 2, 3];
console.log(areEqual(arr1, arr2)); // true
console.log(areEqual(arr1, arr3)); // false
