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

You could take the delta of the check with the wanted value at top.

var data = ["email", "role", "type", "name"];

data.sort((a, b) => (b === 'role') - (a === 'role'));

console.log(data);
