async/await lets an async function pause for an asynchronous result without blocking the JavaScript engine. The async keyword marks the function; await marks each task whose result it needs. Promises and generators provide the underlying model, without requiring you to write their coordination boilerplate. section 6.4.1 section 6.4
(async function (){
try {
const ninjas = await getJSON("data/ninjas.json");
const missions = await getJSON(missions[0].missionsUrl);
console.log(missions);
}
catch(e) {
console.log("Error: ", e);
}
})()
