$ { } I'm a little confused by this.

In a template literal, an expression surrounded with "${" and "}" will be replaced by it's value. For example:

var name = "Joe";
var food = "cookies";
console.log(`My name is ${name} and I like ${food}.`);
// the above should log: "My name is Joe and I like cookies."

This replacement process is called "interpolation".
