Im currently playing around with fetch and was wondering how i can make the callbacks a bit cleaner but still use arrow function. For example i want to make a loop on the success. What syntax should i use?
Code
fetch(url).then(res => res.json())
.then(data => console.log(data.items))
.catch(e => console.log('error'))
There's not much else to do than use a couple of curly brackets and iterate in the usual way
fetch(url).then(res => res.json())
.then(data => {
for (const item of data.items) {
// stuff
}
})
.catch(e => console.log('error'))
You could of course put that in a function and call the function instead, if that makes you happier.
