const { default: fetch } = require("node-fetch");

/* The Async-Await Approach was introduced in ES8 (ECMAScript 2017) */

/*

Like Generators, this approach allows execution to be paused and resumed.

In essence, these features are syntactic sugar on top of promises.

An async function can also be decomposed into a generator/promise implementation.

The await keyword pauses the async function execution until the Promise
is resolved or rejected. Other tasks are still able to run in the meantime.
