JavaScript move an item of an array to the front

Question

I want to check if an array contains \"role\". If it does, I want to move the \"role\" to the front of the array.

var data= [\"ema         


        

Answer 1

let data = [0, 1, 2, 3, 4, 5];
let index = 3;
data.unshift(data.splice(index, 1)[0]);
// data = [3, 0, 1, 2, 4, 5]
