I have been studying promises, await and async functions. While I was just in the stage of learning promises, I realized that the following: When I would send out two requests, there was no guarantee that they would come in the order that they are written in the code. Of course, with routing and packets of a network. When I ran the code below, the requests would resolve in no specific order.
const getCountry = async country => {
await fetch(`https://restcountries.com/v2/name/${country}`)
.then(res => res.json())
.then(data => {
console.log(data[0]);
})
.catch(err => err.message);
};
getCountry('portugal');
getCountry('ecuador');
At this point, I hadn’t learned about async and await. So, the following code works the exact way I want it. Each request, waits until the other one is done.
Is this the most simple way to do it? Are there any redundancies that I could remove? I don’t need a ton of alternate examples; unless I am doing something wrong.
await fetch(`https://restcountries.com/v2/name/${country}`)
.then(res => res.json())
.then(data => {
console.log(data[0]);
})
.catch(err => err.message);
};
const getCountryData = async function () {
await getCountry('portugal');
await getCountry('ecuador');
};
getCountryData();
Thanks in advance,
