Javascript shortcut, to append string into all the values of array?

I have an array = ["a", "b", "c"];

What I want is i have an string let us say "Hello", that I want to append to each and every value of this array.

My expected output is something like

["Hello_a", "Hello_b", "Hello_c"]

Is there any shortcut in javascript to perform this operation, without using any loop .

Any help is appreciated !




Try to use at this context,

var yourArray = ["a", "b", "c"];
var transformed ={
  return "Hello_" + item;
console.log(transformed); // ["Hello_a", "Hello_b", "Hello_c"]

Also you can use fat Arrow functions if users of you are updated with latest browsers.

var yourArray = ["a", "b", "c"];
var transformed = => "Hello_" + item);
console.log(transformed); // ["Hello_a", "Hello_b", "Hello_c"]

As a side note, you have to sure about arrow functions that it will forcibly use lexical this inside of it.
