How to append strings in JavaScript?
One of the coolest things about ES6 is that it gives us a new way to create strings with dynamic values. These are called template literals, and they are awesome!
let firstName = 'John';
let lastName = 'Doe';
let fullName = `${firstName} ${lastName}`;
// Output: 'John Doe'
