Class Loader

[[Loader]] makes it easier to add Google Maps JavaScript API to your application dynamically using Promises. It works by dynamically creating and appending a script node to the the document head and wrapping the callback function so as to return a promise.

const loader = new Loader({
  apiKey: "",
  version: "weekly",
  libraries: ["places"]
});

loader.load().then((google) => {
  const map = new google.maps.Map(...)
})
