Arrow Functions

ES6 introduced arrow function syntax, a shorter way to write functions by using the special “fat arrow” () => notation.

Arrow functions remove the need to type out the keyword function every time you need to create a function. Instead, you first include the parameters inside the ( ) and then add an arrow => that points to the function body surrounded in { } like this:

const rectangleArea = (width, height) => { let area = width * height; return area; };

It’s important to be familiar with the multiple ways of writing functions because you will come across each of these when reading other JavaScript code.
