Arrow Functions in JavaScript

An arrow function expression is a compact alternative to a traditional function expression, but is limited and can't be used in all situations.

For Example,

const materials = [
    'Hydrogen',
    'Helium',
    'Lithium',
    'Beryllium'
];

console.log(materials.map(material => material.length));
// expected output: Array [8, 6, 7, 9]
