Move first item in array to be last

Question

Result:

Code:

window.dataLayer = window.dataLayer || [];
    window.dataLayer.push({
        'event': 'clientId',
        'clientId': SlicedCookie
    });
    

Question: How do I move '0' to be the last item in the array?

Answer 1

shift the first element, and push it on to the end.

const arr = [1, 2, 3, 4];

arr.push(arr.shift());

console.log(arr);

Answer 2

After having the full array, do this to move the first item to last:

window.dataLayer.push(window.dataLayer.splice(0,1)[0]);

Answer 3

I don't clear of your example but as I understand you could use Array.prototype.splice and Array.prototype.push for achieving this requirement.

const data = [2, 3, 4, 5];
const item = data.splice(0, 1);
data.push(item[0]);

console.log(data);
