// 1.using revrese methd?

// 2. Using a Loop:

reverse.push(arr[i]);

console.log(usingLoop([2, 4, 6, 3, 2, 6, 4, 3]));
// 3. Using the reduce() Method:

}
console.log(ReduceMethod([2, 4, 6, 3, 2, 6, 4, 3], "method"));
// 4. Using Recursion:
function reverseArrayUsingRecursion(arr) {

return []
}
const element = arr.pop()
return [element, ...reverseArrayUsingRecursion(arr)]
}
console.log(
