A code snippet that rotates all elements in an array n many times.

shift.js

let firstArr = [
    1,
    2,
    3,
    4,
    5
]

// shift 1: 23451
// shift 2: 34512
// shift 3: 45123
// shift 4: 51234

// n is the number of times to shift
function shift(n) {
    for (let i = 0; i < n; i++) {
        let firstEl = firstArr.shift();
        firstArr.push(firstEl);
    }
    console.log(firstArr);
}

shift(4);
