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

If you don't want to alter the existing array, you can use ES6 destructuring with the filter method to create a new copy while maintaining the order of the other items.

const data = ["email", "role", "type", "name"];
const newData = ['role', ...data.filter(item => item !== 'role')];
