You can use length and every method of arrays to compare two scalar(compared directly using ===) arrays. The combination of these expressions can give the expected result,
1 2 3 4 5 | const arrayFirst = [1,2,3,4,5]; const arraySecond = [1,2,3,4,5]; console.log(arrayFirst.length === arraySecond.length && arrayFirst.every((value, index) => value === arraySecond[index])); // true |
If you would like to compare arrays irrespective of order then you should sort them before,
1 2 3 4 | const arrayFirst = [2,3,1,4,5]; const arraySecond = [1,2,3,4,5]; console.log(arrayFirst.length === arraySecond.length && arrayFirst.sort().every((value, index) => value === arraySecond[index])); //true |
