Generators can yield promises which can work with the "for await of" loop syntax. This lesson shows how all the pieces fit together and explains why the async function*
syntax can be necessary for certain situations.
async function* users() { let names = ["johnlindquist", "eggheadio"] for (let name of names) { let response = await fetch(`https://api.github.com/users/${name}`) yield response.json() } } async function start() { for await (let user of users()) { console.log(user.name) } } start()
