At the ES6 course by Wes Bos I learned about promises. They are used when fetching JSON or Ajax files. It is basically something that will now and between the end of time, so in the future, but probably not immediately.
.then() function will only run when the data comes back
catch()it will catch the error
postsPromise
.then(data => data.json())
.then(data => {console.log(data) })
.catch((err) => {
console.log(err);
})
Or:
p
.then(data => {
console.log(data);
})
.catch(err => {
console.error(err);
})
For now this seems a little difficult for me but I will study them more.
And at the Web Development Bootcamp I finished the Circles page, and used Howles.js to add cool sounds to the circles.
sound: new Howl({
src: ['sounds/zig-zag.mp3']
}),
Cheers!
