var arr1 = [];
for (let i = arr.length - 1; i >= 0; i--) {

}
console.log(arr1);

array reverse with for loop

function reverseArray (arr) {
    var newArr = [];
    var inArr = arr;
    console.log(inArr);
    for (i = 0; i < arr.length; i++) {      
        newArr[i] = inArr.pop(i);       
    }   
    return newArr;
}
reverseArray(["A", "B", "C", "D", "E", "F"]);

// OUTPUT: ["F", "D", "E"]
