let num1 = [23, 3, "js", 1];
let num2 = [23, "js", 3, 1];

function check(a) {
return num2.includes(a);
}

function similar_not(array1, array2) {
return array1.length !== array2.length ? "not equal" : array1.every(a => check(a))


}

console.log(similar_not(num1, num2));

Very good basic fundamental really enjoying

[jayatighosh]

easiest way --
function equalArr(one, two){
let arr1 = one.toString();
let arr2 = two.toString();
if(arr1 == arr2){
return 'Equal';
}
else{
return 'Not Equal';
}
}
console.log(equalArr([1, 2, 3, 4, 5], [5, 4, 1, 2, 3])); // Not Equal
console.log(equalArr([5, 4, 1, 2, 3], [5, 4, 1, 2, 3])); // Equal

const arr1 = [3, 9, 7]
const arr2 = [7, 3, 9]
const arr =
console.log(arr);
if(arr1.length === arr.length && arr2.length === arr.length){
console.log("Equal");
}
else{
console.log("UnEqual");
}

output:
[ 3, 9, 7 ]
Equal

!arr1
.map((v, i) => {return arr2[i] == v;})
.includes(false);
