Read array values in a loop in JavaScript

Question

I have an array in JavaScript that have defined these values:

var myStringArray = [\"1\",\"2\",\"3\",\"4\",\"5\",\"6\",\"7\",\"8\",\"9\",\"10\"];

Answer 1

If you want the immutable way to achieve your circular looping

function loopArray(arr, step=3) {
    let i = 0;
    return function inner() {
        for (let j = 0; j < step; j++) {
            console.log(arr[i]);
            i = (i + 1) % arr.length;
        }
    };
 }

const func = loopArray(["1","2","3","4","5","6","7","8","9","10"], 3);
func();
func();
func();
func();
func();
