ES 2015 Examples - Arrow functions

A simple example with one parameter, using template literals to return the result.

let arrowFunction1 = (x) => {
  return `Hello ${x},<br> from the first arrow function`;
}

Or even without the (), as there's only one parameter, x.

let arrowFunction1 = x => {
  return `Hello ${x},<br> from the first arrow function`;
}

Or just on one line.

let arrowFunction1 = x => `Hello ${x},<br> from the first arrow function`;

RESULT: arrowFunction1('John Doe')

Using two parameters.

let arrowFunction2 = (x,y) => {
  return x + y;
}

Or even shorter:

let arrowFunction2 = (x,y) => x + y;

RESULT: arrowFunction2(13,34)

Without parameters:

let arrowFunction3 = () => "I'm function three...";

RESULT: arrowFunction3()
